The simulated results show that the exact modulation scheme can be identified for lower SNR. The performance was examined for Additive White Gaussian Noise (AWGN) channel based on the confusion matrix, throughput of the algorithm and the Receiver Operating Characteristics (ROC). When SNR is above 3 dB, the probability of detection is proved to be more than 0.984. The parameters of the developed algorithm has been compared with existing algorithms and found that the proposed algorithm can be considered to be the suitable identification method for M-ary Shift Keying with lower SNR (signal-to-noise ratio).]]>Azzouz, E.E. and A.K.
