基于信号I、Q通道信号分布的MPSK信号分类

Classification of MPSK Signals Using the Distribution of in_phase and quadrature signals

本文针对MPSK信号的识别,通过对MPSK信号I、Q通道信号的分布规律进行分析,寻找到一种在低信噪比下仍然具有较高识别率的分类准则。该分类准则首先根据M≤2和M≥4信号的特点进行粗识别,再根据各类信号在经过I、Q通道后的分布规律最后进行识别。计算机仿真计算了算法的性能。

A classification rule is proposed for MPSK signal by the distribution of MPSK signals through in_phase and quadrature channels. At first, identify the value of M rudely based on the discrimination between M≤2 and M≥4 signal, then classify MPSK signals by the distribution of in_phase and quadrature signals . Computer simulation has evaluated the performance of the algorithms.
