Step 203, the spectrogram of more each Preset Time point, if wherein there is each frequency peak in spectrogram within the scope of up frequency of utilization all to undergo mutation, then determines that wireless telecommunications system is subject to the interference of the whole frequency range of time domain burst.
In this step, the spectrogram of more each Preset Time point, up frequency of utilization scope in certain each spectrogram is identical, if wherein the peak value of each frequency all there occurs sudden change relative to the peak value of corresponding same frequency within the scope of the up frequency of utilization in other spectrogram within the scope of up frequency of utilization in a certain or certain several spectrogram, then illustrate that this wireless telecommunications system receives the interference of the whole frequency range of time domain burst.
In the present embodiment, according to smaller interval, as being greater than 1FPS (Frame Per Second: the data frame number of each second), upward signal is sampled, and then obtain the spectrogram of sampled data of each time point, as the spectrogram in the n-th (n is positive integer) moment, the spectrogram in the (n+1)th FPS moment, the spectrogram in the n-th+2FPS moment ... the spectrogram in the n-th+nFPS moment, wherein n is positive integer.After obtaining the spectrogram in this nFPS time period, each spectrogram is compared, if a certain spectrogram, in spectrogram as the n-th+5FPS moment, in this spectrogram, within the scope of up frequency of utilization, the peak value of all frequencies (f1 ~ fn) is all undergone mutation (for wherein a certain frequency relative to the peak value of same frequency (f1 ~ fn) corresponding in other spectrogram, peak value as the spectrogram medium frequency f1 in the n-th+5FPS moment is undergone mutation relative to the peak value of other frequency diagram medium frequency f1), then illustrate that this wireless telecommunications system receives the interference of time domain burst in the n-th+5FPS moment, and whole frequency range all receives interference.
