摘要：In this paper we propose an algorithm for the classification of QAM signal in the presence of Gaussian noise. The additive noise is modeled by Gaussian mixture distribution. A log likelihood algorithm is used to classifying the signal on the basis of decision ¨Ctheoretic approach and develop a schematic structure of classifier for M-array QAM signals. The performance is evaluated in terms of probability of successful classification. We evaluate the performance of the classifier based on the amplitude density function of received signal
