The method includes: demodulating an input radio-frequency signal to acquire a demodulated signal; 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; and performing anti-interference processing on an interfered signal, wherein a signal anti-interference method further includes: after deconvolving the interfering detection signal, performing subtraction or inverse superposition on the detection signal and the first signal, and filtering out the interfering signal to acquire a third signal; and modulating the third signal to acquire an output radio-frequency signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication anti-interference detection method and device","description":"Provided are a communication anti-interference detection method and device.
