Multi-modulus Based Hybrid Blind Equalization Algorithm for High-Order QAM Signals
摘要
Abstract
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 multimodulus 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.关键词
