Problems solved by technology

[0002] With the continuous development of current communication equipment, the complex and dynamic electromagnetic environment has brought great challenges to the design of broadband wireless communication systems
Due to the relatively wide coverage of the operating spectrum of the broadband wireless communication system, there may be other signals that are complexly interleaved in the external environment, which will further increase the probability of the system being interfered
A variety of interference signals will directly affect the correct transmission of useful signals and reduce the efficiency of signal transmission
[0003] In the original communication field, the interference detection in the prior art requires the extraction of a large number of artificial interference features, and the pressure of artificially constructing features is relatively high, resulting in low accuracy and slow detection speed of interference monitoring in the prior art
