摘要
分析了军事通信中传统恒模盲均衡算法(CMA)的基本原理,并针对此算法收敛速度慢、收敛速度与稳态剩余误差之间存在矛盾的缺点,提出一种改进的变步长恒模盲均衡算法(VASCMA)。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收敛效果。
The basic principle of the traditional constant modulus blind equalization algorithm （CMA） is analyzed,and an improved CMA with varying step size （VASCMA） is put forward according to CMA＇s defect that it has a slow rate of convergence and a contradiction between the convergence rate and accuracy. Theoretical analysis and simulation results show that the improved algorithm has better convergence effect and performance than the CMA.
