Abstract :
A modulation recognition method based on cyclic spectral features is presented to solve the problem in modulation recognition for time-frequency overlapped dual-signal in co-channel. Aiming at the OQPSK/MSK signals in co-channel, a new classification feature is constructed using the impact of the different symbol weighting pulse in the cyclic spectrum. Theoretical analysis and experiment results verified the reasonable and efficient of the presented method.
