Paper Abstract

Aiming at the problem of convergence difficulty and big the residue MSE existed in high-order QAM signal equalization and on the basis of analyzing on the MMA, T/4FSE and coherent integration algorithm, Coherent Integration based T/4 Fractionally Spaced Multi-Modulus blind equalization Algorithm (CI- T/4FSMMA) is proposed in this paper. In the proposed algorithm, the fractionally spaced multi-modulus equalizer is union with the coherent integration algorithm. The simulation results of underwater acoustic channel with 128 QAM signal have shown that the proposed algorithm has not only faster convergence speed but also the smaller residue MSE error.
