摘要
We proposed an algorithm using Renyi entropy to distinguish the M-QAM signals in this article. There is no requirement of prior information of the parameters of the signal, because the method we proposed making Wigner-Ville distribution time-frequency transform to signal, then calculate the Renyi entropy, and the last the theory of Dempster-Shafer evidence was used to classify the signals. The results of the simulation show that this method is strongly able to recognize M-QAM signals in the existence of additive white Gaussian noise (AWGN), and the proposed method has a better recognition effect in the low SNR compared with other QAM signal recognition method.
