Multi-modulus Based Hybrid Blind Equalization Algorithm for High-Order QAM Signals

Wang Bin,Ge Lindong,Huo Yajuan(Institute of Information Engineering,Information Engineering University of PLA,Zhengzhou,450002,China)  
For improving the equalization performance of high-order QAM signals,a new multi-modulus based hybrid blind equalization algorithm is proposed.The algorithm uses a new weight factor definition method to improve the weighted multi-modulus blind equalization algorithm(WMMA) and combines it with the decision directed algorithm to construct a new multi-modulus hybrid blind equalization cost function for updating the equalizer coefficients.Compared with other blind equalization algorithms,the new algorithm reduces the residual error and improves the adaptive capacity to different modulation orders.Furthermore,the convergence rate increases.Simulation results prove the feasibility of the new algorithm.
