Abstract
In this paper, we propose an algorithm to perform modulation classification on a 5-class problem consisting of AM, 2-PSK, 4-PSK, 8-PSK and 16-QAM modulation schemes using a combination of features based on the first order cyclostationarity, second- and higher-order moments, and then extend the idea of classification to an intelligent receiver which classifies and demodulates the signal without prior information regarding the transmitted signal.
