摘要

提出了一种瑞利衰落信道中MQAM信号的自动分类方法。该方法的优点在于,通过设计由高阶矩组成的特征向量,不需要先验地获取信号参数的知识,并且是一种简单、低复杂度、鲁棒性好的方法。计算机仿真结果表明,该方法比现有方法具有更高的分类精度。

A New Method for Identification of MQAM Signals in Rayleigh Fading Channel
This paper presents a method for the automatic classification of MQAM signals in Rayleigh fading channel. The advantage of our method is that, by designing a feature vector which is composed of higher order moments, we do not have to acquire a priori knowledge of signal parameters, what is more, it is a simple, very low complexity, robust method. Computer simulations are made and the results show that our method can reach much better classification accuracy than the existing methods.
