For the modulation mode identification for OFDM subcarrier signals
ajoint recognition algorithm with high-order moments and high-order cumulants combined is proposed.This algorithm first distinguishes MPSK(M =2
4)
64QAM and 16QAM by using high-order moment-based feature and then distinguishes BPSK and QPSK by using high-order cumulant-based feature.Theoretical derivation and analysis indicate that this algorithm is insensitive to multipath fading and AWGN.Computer simulation results show that the proposed algorithm has high recognition performance under the multipath channel condition.
