Abstract
According to the signal characteristics of power frequency communication, in order to solve the problem of poor anti-interference ability of time-domain difference method, a time-frequency detection method based on wavelet scale spectrum rearrangement is proposed. This paper discusses the reason why the accuracy of time domain and frequency domain information of wavelet transform restrict each other. The scale spectrum is rearranged to the center of gravity of local energy to obtain more accurate time-frequency information. The characteristics of scale spectrum rearrangement algorithm are analyzed in detail, and the efficiency of the detection method is verified by the actual communication experiments.
