基于T/2分数间隔的不同变步长盲均衡算法
A different variable step size blind equalization algorithm based on the T/2 fractionally spaced
摘要
Abstract
Aiming at the contradicted issues of fixed step in the convergence speed and residual error performance requirements,a different variable step size blind equalization algorithm is proposed based on T/2 fractionally spaced equalizer (FSE) and multimodulus algorithm (MMA).Variable step size items utilize the nonlinear function relationship of error function or equalization output to adjust step size adaptively.It is simulated with QPSK signals,the simulation results show that variable step size blind equalization algorithm has better convergence and less mean square error than fixed step blind equalization algorithm and the algorithms have different equalization performance when variable step size items are different.关键词
