摘　　要：针对传统修正恒模算法(MCMA)收敛速度慢、剩余码间干扰大的缺点,在双模式修正恒模算法(MCMA+DD-LMS)的基础上引入局部信息量和变步长的思想,提出了一种基于修正多模算法(MMMA)的双模式变步长修正多模算法(VS-MMMA+DD-LMS)。经过理论分析和实验仿真,证明改进后的算法较传统算法具有更好的均衡效果。To solve modified constant modulus algorithm’s problems that it has a slow convergence and has large inter-symbol interference,this paper put forward a varying step dual-mode blind equalization lgorithm based on modified multi-mode algorithm from the introduction of local information and variable step. Through theoretical analysis and experimental simulation,proved that the improved algorithm has better effect compared with traditional algorithm.
