1. A signal interference detection method, comprising:
demodulating an input radio-frequency signal to acquire a demodulated signal; and
convolving 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.
