Aiming at the multipath fading channel, the signal modulation recognition based on multi-antenna diversity receiving technology is studied and the classifier based on multi-antenna diversity receiving modulation recognition is analyzed and designed. Computer simulation results show that for multi-fading channels, multi-antenna diversity receiver modulation recognition can improve the accuracy of the identification parameters, which can effectively reduce the modulation recognition requirements of the observed data length and signal to noise ratio, and improve the accuracy of modulation recognition .
