Abstract

The method of neural network detecting on the basis of complex envelope analysis is presented for M-ary PSK signals in general case. Multilayered perceptron is used as the detector. Estimations of noise robustness and carrier deviation robustness are made for presented method. Results of computer simulations of detecting quaternary PSK signal show efficiency of the presented method.
