摘要
常模算法是最常用的盲均衡算法之一,针对常模算法剩余误差较大、收敛速度慢以及误码率高等缺点,引入变动量因子对其进行修正,并采用无线数字通信系统输出信号对其进行仿真验。仿真结果表明:引入变动量因子后,常模盲均衡算法的剩余误差有所降低,误码率显著降低,收敛速度有一定程度的提高。
Constant modular algorithm（CMA） is one of the most frequently used blind equalization methods.The paper adopts the variable momentum factor to the CMA considering its disadvantage of large surplus error,low convergence rate and low byte-error rate,etc,and simulates the improved equalization method with output signals transferred by wireless digital communication system.The simulation results demonstrate the significant cutting down of the byte-error rate when the variable momentum factor is adopted to the CMA,the surplus error is also lowered,and at the same time the convergence rate is improved.
