Abstract :
This paper proposes a joint blind equalization and modulation identification algorithm for higher order QAM modulated signals in multi-path environments. Compared with the existing algorithms, the complexity of the proposed algorithm is reduced and the proposed algorithm is robust to carrier phase offset in the multi-path channels. Simulation results demonstrate the feasibility at middle or high SNR (signal to noise ratio)
