Below in conjunction with Figure of description, the embodiment of the invention is elaborated.
The process in the location interference source that Fig. 1 provides for the embodiment of the invention, this process may further comprise the steps:
S101:, determine the wave angle that comes of the interference signal correspondence that gathers described each collection point according to the signal that gather each collection point.
Determine the interference signal correspondence that gathers each collection point come wave angle the time, working frequency range according to current mobile communication equipment, in the signal that gather each collection point, filter out the interference signal that described interference band is caused interference, and the interference signal that will filter out from each collection point is carried out quantification treatment, according to each interference signal after the quantification treatment, determine the wave angle that comes of the interference signal correspondence that gathers described each collection point.
S102: at each collection point, the interference signal of gathering according to this collection point and with this collection point is corresponding comes wave angle, determines the interference source path locus through this collection point;
Wherein determine to comprise through the interference source path locus of this collection point: with the end points of described collection point as ray, the wave angle that comes of the interference signal correspondence of corresponding described collection point is an angle, determines the interference source path locus through described collection point.
S103: determine the attribute information of each interference signal in each collection point, and according to the attribute information of each interference signal in described each collection point of determining, and the described interference source path locus of determining, determine the position of interference source.
The attribute information of each interference signal comprises time-domain information, frequency domain information or the amplifier distortion information etc. of each interference signal.
The position of described definite interference source specifically comprises: time-domain information, frequency domain information or the amplifier distortion information of adding up each interference signal in each collection point, the intersection point of interference source path locus that will have the interference signal correspondence of identical time-domain information, frequency domain information or amplifier distortion information is as the position of interference source.
When drawing the interference source path locus, on map, determine the position of each collection point, to determine the interference source path locus according to the orientation angle that comes wave angle according to the latitude and longitude information of each collection point.Because the path locus of the interference source of determining is a ray, then certain on this ray a bit may be the position at interference source place.Can determine the particular geographic location of this some during the position in concrete location interference source according to the latitude and longitude information of the intersection point of the interference source path locus of determining, with the position of this geographical position as the interference source place.
Because in embodiments of the present invention at each collection point; when having determined through behind the interference source path locus of this collection point; can there be intersection point in the interference source path locus that different acquisition point is corresponding, generally with the intersection point of this interference source path locus position as interference source.And because interference signal can be received the building refraction, or the influence of signal stack, therefore there is false position of interference source in the intersection point of the interference source path locus of determining.The embodiment of the invention is in order effectively to remove false interference source, at each collection point, determine through behind the interference source path locus of this collection point, added up the time domain of each interference signal of each collection point collection, attribute informations such as frequency domain information or amplifier distortion information, owing to have identical time domain, the interference signal of attribute informations such as frequency domain information or amplifier distortion information just may be the interference signal that same interference source sends, and will have identical time-domain information, the intersection point of the interference source path locus that the interference signal of frequency domain information or amplifier distortion information is determined, position as interference source, thereby effectively eliminated because the interference that building causes the refraction of signal, and the different interference of disturbing stack generation between the source signal, and then interference source locating accuracy and accuracy have been improved.
The terminal of carrying out interference source location in embodiments of the present invention can be carried out the location of interference source in real time, also can carry out the location of interference source when being determined to current mobile communication equipment and being interfered, and concrete implementation process can be selected as required flexibly.Whether wherein current mobile communication equipment is interfered can be according to current mobile communication equipment received signal intensity indication (Received Signal Strength Indicator, RSSI) whether less than preset threshold, judge, when current mobile communication equipment received signal intensity is indicated less than setting threshold, determine that then current mobile communication equipment is interfered, otherwise, determine that current mobile communication equipment is not interfered, current mobile communication equipment can be the base station.The terminal of carrying out the interference source location can be the base station, also can be for having the other-end equipment that smart antenna and current mobile communication equipment close on.
Can pass through the smart antenna acquired signal in embodiments of the present invention, because smart antenna may comprise a plurality of passages, for example for the time-division that comprises 8 passages (Time Division, TD) smart antenna, adopt the smart antenna acquired signal in each collection point, and after having obtained the signal of gathering each collection point, owing to need to determine cause the interference source of interference, and has only just meeting phase mutual interference between the signal of similar frequency bands to the mobile communication equipment of work at present frequency range.Therefore need be according to the working frequency range of current mobile communication equipment, for example be global system for mobile communications (Global System for Mobile Communications, GSM) frequency range, Digital Cellular System (Digital Cellular System, DCS) frequency range or TD frequency range etc., in the signal that each smart antenna collects by each passage, filter out the interference signal that the work at present frequency range is caused interference, promptly in the signal that each passage collects, will come out with the filtering signals of the working frequency range similar frequency bands of current mobile communication equipment, with this signal that filters out as the interference signal that mobile communication equipment before deserving is caused interference.
After the interference signal of this frequency range filters out in each passage,,, need handle the interference signal that each passage filters out and obtain digital signal in order to satisfy the demand of data processing because the interference signal of this each passage that filters out is an analog signal.The process of this processing comprises: the analog radio frequency interference signal of this frequency range of obtaining after filtering in each passage is down-converted to intermediate-freuqncy signal, to the digital signal that the intermediate-freuqncy signal that obtains after each passage frequency conversion is sampled, thereby quantification treatment obtains corresponding each passage, this analog signal conversion is that the process of digital signal does not here just describe in detail.
The signal that each passage by smart antenna collects, there is nonsynchronous problem probably in the difference that is subjected to the collecting device antenna oscillator, in order to guarantee the accuracy of interference source location, each passage of smart antenna need be compensated processing by the signal that antenna oscillator receives, the signal Synchronization that each passage is gathered, can carry out quantification treatment to each interference signal in the invention process after, the digital signal of each passage that obtains compensates.
The compensation method of Cai Yonging comprises in embodiments of the present invention: passage consistency error compensation, asynchronous compensation of sample time and the inconsistent compensation of frequency response etc.Wherein passage consistency error compensation is determined the otherness of interchannel by the acquisition performance of each passage in the smart antenna is tested, and according to this otherness the signal that respective channels receives is carried out passage consistency error compensation.Equally when the signal to each passage carries out sample time asynchronous compensation, determine the otherness in each passage sample time, the signal of respective channel is carried out asynchronous compensation of sample time according to this otherness.When adopting TD smart antenna received signal, because the TD smart antenna is according to transmitting and receiving the design of TD frequency band signals, therefore this TD smart antenna is when receiving the signal of other frequency ranges, for example during the signal of GSM frequency range, its frequency response, difference can appear in the phase response performance, be specifically as follows when receiving the signal of other frequency ranges, the electrical characteristic of this smart antenna is different with the electric property that receives the TD frequency band signals, therefore, need test the electric property that smart antenna is gathered other frequency band signals, according to test result, the electric property of this smart antenna being gathered other frequency band signals compensates, and obtains the signal of each passage of obtaining after the electric property compensation.
The interference signal of gathering according to each passage of each smart antenna after the compensation, adopt the spatial frequency spectrum algorithm, for example MUSIC algorithm or ESPRIT algorithm, arrive the time delays in different intelligent antenna a period of time according to the signal of same interference source, determine corresponding each smart antenna collection interference source signal correspondence come wave angle, wherein this to come wave angle be the incoming wave angle of the signal of intensity maximum in the interference source signal, this angle is the angle of this interference signal and smart antenna normal direction.
Above-mentioned interference signal to the smart antenna collection is handled, and definite mode of coming wave angle of determining the interference signal correspondence of corresponding each smart antenna also has open in the prior art, when the interference signal correspondence of having determined corresponding each smart antenna collection come wave angle the time, can be according to the position of each smart antenna, and this comes the direction of wave angle, determine with this smart antenna position to be end points, the incoming wave angular direction is the ray of direction, promptly determines the interference path track through this collection point, smart antenna place.Because after the interference path track is determined, should be that the interference source path locus that the ray of end points constitutes can exist intersection point with each collection point, this intersection point can be used as the location point at interference source place.
But owing to there is the influence of disturbing factor such as building refraction in the mobile communications network, thereby make the position of definite interference source inaccurate, promptly the position at the interference source place of Que Dinging may be dummy location, in embodiments of the present invention in order effectively in the position of interference source of the dummy location of determining that comprises interference source, to determine the actual position of interference source, in embodiments of the present invention can be by analyzing the attribute information of the interference signal that each passage of smart antenna collects in each collection point, determine the actual position of interference source, this process specifically comprises:
Analyze the attribute informations such as time-domain information, frequency domain information or amplifier distortion information of the interference signal of each passage collection that obtains after each smart antenna compensation, because have between the signal of identical attribute information and have attribute informations such as identical time-domain information, frequency domain information or amplifier distortion information, be that identical signal is having identical variation characteristic on the frequency domain with on the time domain, and the influence that the signal of same interference source is subjected to identical amplifier distortion also have identical variation characteristic.Fluctuation has appearred in its a certain moment in time domain of first interference signal that receives when a certain passage of first smart antenna, for example this interference signal is constantly recessed at this, then this first interference signal that this first smart antenna is received is given the identification information that is different from other interference signals, second interference signal that receives when a certain passage of second smart antenna also the moment of this in time domain recessed, and recessed amplitude is identical in this recessed amplitude constantly with first interference signal, then also give the identification information identical with first interference signal with this second interference signal that receives of this second smart antenna, think that promptly first interference signal has identical attribute information with second interference signal, first interference signal and second interference signal can be thought the interference signal that sends out for same interference source.Adopt said method all to give identification information with each interference signal that each smart antenna receives.
The above-mentioned definite variation characteristic of interference signal on time domain or frequency domain, can be as required step-up error scope flexibly, the fluctuation of a certain direction has appearred in first interference signal of for example a certain smart antenna collection in the position of 20MHz, second interference signal of another smart antenna collection unidirectional fluctuation occurred in the position of 20.56MHz, when its 1MHz of error range of being provided with, then two first interference signals and second interference signal can be thought the interference signal of sending for same interference source, give same identification information with two interference signals.
When the frequency information of the signal of determining each interference source path locus correspondence, this signal is carried out fast fourier transform (Fast Fourier Transform, FFT), obtain the spectral characteristic of this signal, spectral characteristic according to this signal, promptly determine the performance characteristic of each interference signal in frequency domain, determine this signal frequency-domain information.
Determining through behind the interference source path locus of collection point, smart antenna place, owing to have intersection point between the interference source path locus of the interference signal correspondence that different acquisition point is gathered, the position of each intersection point correspondence may be the position of interference source, has identical identification information owing to have the signal of same alike result information in embodiments of the present invention, and the interference signal that the interference signal with same alike result information may be sent for same interference source, so the position of the intersection point of the interference source path locus that the interference signal with same identification information can be determined, as the position at interference source place.
Above-mentioned implementation process, localization method at interference source, when determining the attribute information of the interference signal that each smart antenna is gathered, accuracy in order to ensure the interference source location only needs at a kind of attribute information, promptly determine a kind of attribute information of the interference signal that gather each smart antenna collection point, for example determine the frequency domain information of each interference signal, determine that each interference signal is to identification information that should attribute information, according to the different identification information of interference signal, determine the actual position of interference source.Can certainly adopt by determining the two kinds or more of attribute informations of the interference signal that each smart antenna is gathered, carry out the interference source location.
Definite process of position of interference source for example shown in Figure 2, in Fig. 2, comprise two collection points, two interference source path locus have been determined by each collection point, the first interference source path locus 11 of the first collection point correspondence and the second interference source path locus 12, corresponding the 3rd interference source path 21, second collection point and the 4th interference source path locus 22, wherein during the attribute information of the interference signal of gathering at the smart antenna of determining to be positioned at each collection point, determine that first interference signal has the first time domain attribute information in first collection point, second interference signal has the first frequency domain attribute information in first collection point, the corresponding first interference source path locus 11 in the incoming wave angular direction of this first interference signal correspondence, corresponding second path locus 12 in the incoming wave angular direction of the second interference signal correspondence, determine that the 3rd interference signal has the first time domain attribute information in second collection point, the 4th interference signal has the first frequency domain attribute information in second collection point, corresponding the 4th path locus 22 in the incoming wave angular direction of corresponding the 3rd interference source path locus 21, the four interference signal correspondences in the incoming wave angular direction of the 3rd interference signal correspondence.
When determining position of interference source according to the interference source path locus of determining, since in first collection point in first interference signal and second collection point the 3rd interference signal have identical time domain attribute information, therefore the intersection point in the interference source path determined, the incoming wave angular direction of these two interference signal correspondences can be defined as the first position of interference source position point, simultaneously in first collection point in second interference signal and second collection point the 4th interference signal have identical frequency domain attribute information, therefore the incoming wave angular direction of these two interference signal correspondences determines that the intersection point in the interference source path of eating can be defined as the location point at the second position of interference source place, as shown in Figure 2.
In the embodiment of the invention when when determining position of interference source, in order to reduce amount of calculation, improve the efficient of interference source location, can in the collection point at smart antenna place, select to carry out the collection point of interference source location, according to the collection point of selecting, determine through this each collection point interference source routing information, and attribute information according to each interference signal in the collection point of this selection, determine the position of interference source, because the collection point of selecting is less, therefore can reduces the amount of calculation of interference source location, and improve the efficient of interference source location, when selecting the collection point, according to the distance of collection point and mobile communication equipment, perhaps according to accuracy of each collection point acquired signal etc. when definite, can also be when reducing interference source location Calculation amount, improve the accuracy of interference source location, here just do not give unnecessary details one by one.
In the embodiment of the invention when the position in location interference source, according to the interference source path locus of determining through the collection point, and the attribute information of the signal of each interference source path locus correspondence, to have same alike result information in the position of the intersection point of disturbing the interference source path locus that signal determines, position as interference source, owing to considered the attribute information of the interference signal of each interference source path locus correspondence, and have only same interference source to produce and just may have identical attribute information through the interference signal in identical path, therefore, the embodiment of the invention has effectively been got rid of building when the location interference source, or the interference of signal stack generation, thereby improved the accuracy of interference source location.
