Research on Modulation Recognition of the MPSK Signals Based on Statistical Analysis

Abstract:

The PSK signals have been applied widely in wireless communication systems, such as in the military and commercial satellite system, the digital short-wave radios, and the ALE system of radio station, etc. This article will be discussed on the problem of how to identify the PSK subclass signal in the situation of non-cooperative communication. In addition, the blind identification method based on Wavelet Transform (WT) and Phase Clustering has been mentioned in the following without knowing any prior information. The first is to obtain the phase mutation phase difference by using WT, and then the modulation recognition of PSK subclass signal will be achieved through the threshold that ground on characteristics of PSK structure. When SNR greater than 2dB, the recognition rate of PSK subclass signal can reach more than 93%, in the condition of white Gaussian noise.
