Research on Modulation Recognition of MPSK Signal Based on Deep Learning
Many scholars at home and abroad have done a lot of in-depth research on signal modulation recognition,and devised a variety of modulation recognition methods.However,among these recognition algorithms,the recognition effect of Multiple Phase Shift Keying(MPSK)signals is not ideal.The article will use a deep learning recognition model to identify the type of MPSK modulation signal using the relevant features of the signal's time-frequency map and constellation map,and make decision fusion based on the recognition results of the time-fre-quency and constellation graphs.The recognition effects of the three methods are compared to achieve substantial improvement of MPSK signal recognition effect.
