  • This paper proposes an identification algorithm for higher order QAM modulated signals based on the improved HY-NCMA blind equalization method in multi-path environments. Compared with the existing algorithms, the equalizer can recover the phase offset and have faster convergence, furthermore, not only are the sample size and the complexity of the proposed algorithm reduced, but also the identification rate is improved by means of the new identification feature. Simulation results demonstrate the efficiency of the modulation identification at middle or high SNR (Signal to Noise Ratio).
