Description
Technical field
Method, a kind of corresponding device and the corresponding computer that the present invention relates to a kind of for receiving radio signal
Program.
Background technique
Use amplitude modulation that usually there is function of search as the AM radio receiver of modulation system, with from set reception
Frequency starts to adjust a now receivable transmitter of laying equal stress on.The frequency stepping that frequency can fix is received herein to improve or drop
It is low.It can for example be examined in new reception frequency now, receive whether field intensity is greater than threshold value and other show the matter of interference
Whether magnitude is less than threshold value.If all standards all meet, it can terminate to search for, wherein reappearing using current frequency.
Summary of the invention
In this context, a kind of method for receiving radio signal is provided using theory presented here, into one
Step proposes a kind of device using this method and the corresponding computer program according to independent claims.It is advantageous
Design scheme is by corresponding dependent claims and following obtains.
The aspect herein proposed provides a kind of method for receiving radio signal, and wherein this method includes following step
It is rapid:
Read the reference information of the signal quality acquired in reference time point about radio signal;
Receive the signal message of the signal quality acquired in current point in time about radio signal;And
The signal quality acquired in current point in time is examined using signal message and reference information, to determine aerogram
Number reproduction quality.
Radio signal can be regarded as amplitude-modulated signal, as the long-wave signal, medium wave signal or shortwave of radio transmitter are believed
Number.The signal quality of radio signal can for example pass through the interference or nothing of the reception field intensity, radio signal of radio signal
The reception field intensities of the adjacent signals of line electric signal characterizes.Reference time point can be regarded as before the current point in time when
Between point.Such as the step of reading, can be repeated with predetermined rhythm, to read multiple reference informations, wherein each reference
The signal quality acquired in other each reference time points of information expression radio signal.Reference information for example can be preparatory
It is stored in determining time period in suitable memory (also referred to as scene memory).The step of reading and receiving can
It is carried out simultaneously or successively with random order.In the step of examining for example radio can be examined by means of different threshold value comparisons
The signal quality acquired in current point in time of signal.Threshold value as used herein is selectable such that radio signal in success
Inspection in have sufficiently high reproduction quality.
The understanding that the aspect introduced herein is based on is that can examine according to the pervious signal quality of radio signal can
The signal quality of received radio signal.Thus the fluctuation of relevant to receiving time signal quality can be obtained and can be wireless
It is taken in the inspection of electric signal.Such as the function of search for controlling radio receiver can be examined in this way, make
The different receiving times obtained in radio signal ensure good reproduction quality always.
The reception of especially AM transmitter can be highly dependent on the daily time.On daytime due in long-wave band, medium wave band
It can be received with the relatively small number of transmitter of decaying in the daytime in shortwave segment limit, and obviously have at dusk and at night
More transmitters can be received.However many transmitters may be lost by serious field intensity, English decline
The interference of (englisch Fading), adjacent frequency or the influence of other electromagnetic interferences.
This signal decaying depending on the daily time can take in the following manner in transmitter search now,
I.e. not only to current obtained signal quality variable (such as receiving field intensity) or other show that the mass value of interference makes sound
It answers, and additionally using the signal message being stored in scene memory, to determine the corresponding quality of reception of transmitter.Signal
Information can for example obtain in the independent signal processing path by reproduction path.
Search can be designed such as to any time in one day in this way all with quality of reception weight good enough
Existing transmitter.
This method is settable to determine the step of examining threshold value using reference information.In the signal quality that current point in time obtains
It can be compared with inspection threshold value.It, can be in inspection herein if being more than to examine threshold value in the signal quality that current point in time obtains
It tests in step to it.Threshold value is examined to can be regarded as the reception field intensity that radio signal must at least have, to examine
It tests in step and tests.Such as it can be according to more than specific field strength threshold value and more than the receivable radio of certain interference threshold value
The quantity regulation of signal examines threshold value.There is low signal matter from the beginning by means of examining threshold value that can prevent from further examining
Amount is to be unsuitable for the radio signal reappeared.Thus the efficiency of this method can be improved.
It is advantageous that being read in reading step about additional radio signals in reference time point or attached
At least one additional reference information for the signal quality for adding reference time point to obtain.It correspondingly can be in determining step further
It is determined using additional reference information and examines threshold value.Additional radio signals can be regarded as the transmission channel for deviateing radio signal.
The signal quality of additional radio signals can not only be obtained in reference time point but also at the additional reference time point offset.It borrows
Help additional reference time point for example and can determine the entirety of the radio reception in the frequency range for including multiple radio signals
Quality.It can be determined herein according to the total quality of radio reception and examine threshold value.Such as when there is only less well to receive
Radio signal when may be selected lower inspection threshold value, or when there are many can good received radio signal when it is optional
Select higher inspection threshold value.

Show the interference of radio signal obtained in current point in time or the reception field intensity of adjacent signals obtained in current point in time.
Receiving field intensity can be regarded as radio receiver (such as long wave, medium wave or short-save receiver) to receive radio signal
The measured value of field intensity.Interference can be regarded as radio signal or with the signal of radio signal interaction expression signal
The measured value of mass attenuation.Adjacent signals can be regarded as its frequency range it is adjacent with the frequency range of radio signal or at least with
Close signal, such as adjacent radio transmitter.It can be comprehensively and with degree of precision true by means of this reference information
Determine the signal quality of radio signal.
It is obtained in another reference time point it is also advantageous that reading in reading step about radio signal
At least another reference information of signal quality.Another reference information can be further used in the step of examining to examine current
The signal quality that time point obtains.By can be in the step of examining by the signal quality obtained in current point in time and at least two
A signal quality previously obtained at other times respectively compares, such as can reliably determine the field strength of radio signal
Degree loss.
According to another embodiment, in reading step another reference information can indicate adjacent signals in another reference
The reception field intensity that time point obtains.It can be by the reception field strength of adjacent signals obtained in reference time point in the step of examining
The reception field intensity of degree and adjacent signals obtained in another reference time point forms field intensity average value.It can determine herein on the scene
