摘要

本文提出了适用于时变信道的自适应递推最小二乘灰色均衡的新思想．以收敛性比较，最小二乘灰色均衡器优于传统的最小二乘均衡器，而以时变信道上的误码率来看，其性能是盲均衡器（按文献［１］，［２］盲均衡思想导出的最小二乘盲均衡器）所不能比拟的，而且也优于传统的均衡器，理论分析及计算机模拟表明，自适应最小二乘灰色均衡器是时变信道上性能优良的均衡方法．

Abstract

A new idea of the adaptive RLS grey equalizer which is suited for time-varying channels has been presented. The convergence perfermance of the RLS grey equalizer is better than that of the classical RLS equalizer. Its symbol error performace is not only much better than that of the RLS blind equalizer whose derivation is based on the literatures[1]and[2]

but also better than that of the classical RLS equalizer. The analysis and simulation indicate that the RLS grey equalizer is a very good equalization method on time-varying channels.
