Claim 8:
9. A communication anti-interference detection device, comprising:
a demodulation module, an interference detection module, an anti-interference module and a radio-frequency circuit processing module;
wherein
the demodulation module is configured to demodulate an input radio-frequency signal to acquire a demodulated signal-;
the interference detection module is configured to convolve a first signal and a second signal to acquire a detection signal, so as to detect whether there is an interfering signal in the input radio-frequency signal, wherein the first signal is a signal acquired by performing inverse Fourier transform on the demodulated signal, and the second signal is a signal acquired by performing phase inversion on a preset baseband signal; and in cases where the detection signal is interfering, the anti-interference module is configured to process the interfering detection signal and the first signal to acquire a third signal, and the third signal is modulated to acquire an output radio-frequency signal, and is processed by the radio-frequency circuit processing module.
