Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The present application provides a signal receiving method, which can be applied to all ad hoc network devices included in a wireless ad hoc network communication system, and the signal receiving method provided by the present application will be described in detail through the following embodiments.
Referring to fig. 1, a flow chart of a signal receiving method according to an embodiment of the present application is shown, where the signal receiving method may include:
Step S101, a radio signal matching with an antenna is received from radio signals from an air interface through a single antenna as a target radio signal.
Wherein the target radio signal comprises at least one radio signal.
In particular, radio signals (i.e., electromagnetic waves) of a spatial electromagnetic field are divided into a plurality of frequency bands, and in the field of radio communications, signals of a specific frequency band need to be selected for preferential locking.
In this step, when a radio signal of the spatial electromagnetic field is transmitted to an ad hoc network device in the wireless ad hoc network communication system, the ad hoc network device can receive a radio signal matching the antenna from the radio signal from the air interface through a single antenna installed by itself.
Alternatively, the process of "receiving a radio signal matched to an antenna from radio signals from an air interface through a single antenna" in this step may include: radio signals within the operating frequency range of the antenna are received from radio signals from the air interface through a single antenna.
That is, the "matching" refers to the radio signal within the operating frequency range of the antenna, for example, if the operating frequency range of the antenna in this step is 350M to 400M, then this step can receive the radio signal within the range of 350M to 400M.
For convenience of the following description, this step defines the received radio signal as the target radio signal. Since the antenna can receive radio signals within a certain frequency band range, the target radio signal received in this step includes at least one radio signal, and optionally, one radio signal may refer to a radio signal of one frequency point.
Step S102, selecting a path of radio signal with the quality larger than or equal to a preset receiving quality threshold from the target radio signal, and receiving and forwarding the target radio signal on a channel where the selected radio signal is located.
Here, the preset receiving quality threshold refers to a receiving sensitivity of the wireless ad hoc network device, where the receiving sensitivity can reflect a receiving capability of the ad hoc network device (used as a receiver) to a weak signal under a specified bandwidth, and when a quality of a radio signal is lower than the receiving sensitivity (i.e., the receiving quality threshold), a situation that the receiver cannot demodulate the radio signal may occur.
Therefore, this step requires selecting a radio signal with a quality higher than the reception quality threshold from the target radio signal, and performing service reception and forwarding of the normal sensitivity service on the channel on which the selected radio signal is located.
It should be noted that, in this step, when one radio signal is selected from the target radio signals, the antenna path may be divided into a plurality of signal paths (in this case, the system receiving sensitivity may be reduced, for example, if the antenna path is divided into two signal paths, the system receiving sensitivity is reduced by 3 dB), based on which, after one radio signal is selected in this step (i.e., the preferential phase is ended), the plurality of signal paths need to be combined into one path (after the signal paths are combined into one path, compared with the case of dividing into multiple paths, the system receiving sensitivity may be improved, for example, the system receiving sensitivity is improved by 3dB after the two signal paths are combined into one path), so that the service receiving and forwarding with normal sensitivity are performed on the channel where the selected one radio signal is located.
In addition, it should be noted that the "target radio signal" in the step of receiving and forwarding the target radio signal on the channel where the selected radio signal is located "may be different from the" target radio signal in the step of selecting a radio signal with a quality greater than or equal to the preset receiving quality threshold "from the target radio signals, because the process of receiving and forwarding the service needs to be performed at multiple times, and the step only needs to select a radio signal from the target radio signals received at a certain time, after the preferential stage is finished, the step may receive and forward the target radio signal received at a subsequent time on the channel where the selected radio signal is located in the whole service receiving and forwarding stage.
The signal receiving method provided by the application firstly receives a matched radio signal from radio signals from an air interface through a single antenna to serve as a target radio signal, then selects one path of radio signal with the quality larger than or equal to a preset receiving quality threshold from the target radio signal, and receives and forwards the target radio signal on a channel where the selected radio signal is located. Because the signal receiving method provided by the application can realize the receiving and forwarding of the target radio signal only by one antenna, compared with the prior art which needs a plurality of antennas, the application improves the utilization rate of the self-networking equipment and reduces the hardware cost.
In addition, the application can adaptively and dynamically adjust the enabling of the receiving channels of the wireless self-organizing network communication system when the target radio signal comprises one radio signal or multiple radio signals in different stages of service, so that the normal service can be received and forwarded on the preferred one receiving channel later, the receiving processing performance of the system is greatly improved, and the overall working efficiency is further improved.
The following is an alternative embodiment of the present application, which describes in detail the above-mentioned procedure of "step S102, selecting a radio signal with a quality greater than or equal to the preset reception quality threshold from the target radio signals".
As described in the foregoing embodiment, in this embodiment, it may be first determined whether the target radio signal is a single radio signal, and if the target radio signal is a single radio signal, that is, the target radio signal includes only one radio signal, the embodiment may determine whether the quality of the target radio signal is greater than or equal to the receiving quality threshold, and if so, the target radio signal is used as the one radio signal selected in this embodiment.
If the target radio signal is not a single radio signal, i.e. the target radio signal comprises multiple radio signals, the process of this embodiment may include: dividing the target radio signal into a plurality of paths of radio signals according to a preset frequency point, and selecting one path of radio signal with the quality larger than or equal to a receiving quality threshold from the plurality of paths of radio signals.
Here, the preset frequency point is a frequency point within the operating frequency range of the single antenna mentioned in the above embodiment.
Specifically, as described above, each radio signal included in the target radio signal may be a radio signal of one frequency point, in this embodiment, some frequency points may be preset, and then signal receiving and forwarding may be performed on a channel corresponding to the preset frequency point.
It should be noted that, the "dividing" provided in this embodiment may specifically be that radio signals corresponding to a preset frequency point are screened out from the target radio signals, that is, optionally, the process of "dividing the target radio signals into a plurality of radio signals according to the preset frequency point" includes: and screening radio signals corresponding to a plurality of frequency points contained in the preset frequency points from the target radio signals, and taking the radio signals corresponding to the screened frequency points as a plurality of paths of radio signals.
In this embodiment, the number of preset frequency points is the same as the number of paths of the radio signals to be screened.
For example, the first frequency point and the second frequency point may be preset, for example, refer to a schematic process diagram of dividing the target radio signal into two radio signals shown in fig. 2a, and a schematic process diagram of selecting one radio signal from the two radio signals shown in fig. 2b, where the first frequency point corresponding to the F1 channel and the second frequency point corresponding to the F2 channel are preset. After the first frequency point and the second frequency point are preset, the radio signals corresponding to the first frequency point and the second frequency point can be screened from the target radio signals, the radio signals corresponding to the screened first frequency point are used as first path radio signals, and the radio signals corresponding to the screened second frequency point are used as second path radio signals.
Optionally, when "selecting a radio signal with quality greater than or equal to the reception quality threshold from among the plurality of radio signals" described above, any radio signal with quality greater than or equal to the reception quality threshold may be selected from among the plurality of radio signals.
Considering that when a radio signal is arbitrarily selected, if the quality of the channel on which the selected radio signal is located is poor, the quality of the received and forwarded signal may be poor, thereby affecting the receiving processing performance of the system. Therefore, in a preferred case, the present embodiment may select, from among the radio signals whose quality meets the reception quality threshold, a radio signal with the best quality, that is, the above-mentioned "selecting, from among the radio signals, a radio signal with a quality greater than or equal to the reception quality threshold" may include:
And a1, determining a radio signal with the quality larger than or equal to a receiving quality threshold from a plurality of paths of radio signals as a radio signal to be screened.
In this step, those radio signals that the receiver is able to demodulate may first be screened out of several radio signals, and the screened out radio signals are defined as radio signals to be screened.
And a2, selecting a path of radio signal with the best quality from the radio signals to be screened.
For example, referring to fig. 2b, if the quality of the F1 channel is better than the quality of the F2 signal, this step may select the F1 signal.
It should be noted that, the above-mentioned processes in steps a1 and a2 are only examples, and are not limiting to the present application, for example, the present embodiment may also select one radio signal with the best quality from a plurality of radio signals, then determine whether the quality of the one radio signal is greater than or equal to the radio signal with the receiving quality threshold, if yes, select the one radio signal with the suboptimal quality from a plurality of radio signals, and repeat the determining and selecting processes until the best radio signal in the radio signal with the quality greater than or equal to the receiving quality threshold is selected as the selected one radio signal.
In summary, the present embodiment comprehensively considers the requirement characteristics of different stages of the service, when only one radio signal is received, if the quality of the one radio signal is greater than or equal to the receiving quality threshold, then the normal sensitivity service is received and forwarded on the channel where the one radio signal is located, and when the multiple radio signals are received, one radio signal can be preferentially selected from the multiple radio signals, so that the normal sensitivity service is received and forwarded on the channel where the one radio signal is located. Therefore, the application can adaptively and dynamically adjust the enabling of the system receiving channel to realize the service scanning preferential and the normal receiving processing after preferential without losing the service.
In addition, the embodiment can also realize service receiving and forwarding based on a single antenna, which makes full use of the hardware processing characteristics of the device, and on the premise of not increasing any hardware cost, in the service scanning preferential locking period and the normal service receiving and forwarding period, according to the demand characteristics of different service stages (the different service stages enable the target radio signal to comprise only one path of radio signal and possibly multiple paths of radio signals), the method can adaptively and dynamically adjust the enabling of a system receiving channel to realize the service scanning preferential and preferential normal receiving processing without losing the service, realize hardware multiplexing and meet the demands of different service stages, greatly improve the receiving processing performance of the system and improve the overall working efficiency of the system.
The embodiment of the application also provides a signal receiving device, which is described below, and the signal receiving device described below and the signal receiving method described above can be referred to correspondingly.
