时变信道的盲均衡

Blind Equalization on Time-Variant Channels

本文把求解接收信号相关矩阵和自适应盲均衡代价函数法结合起来,提出了一种适合时变信道的盲均衡新算法。计算机模拟表明:本文的方法提高了盲均衡的收敛速度,且均衡器在时变HF短波信道上发散时,能在200～300点之内把均衡器恢复到正常工作状态。

This paper,combining the solution of received signals covariance matrix with adaptive blind equalization algorithm,presents a new algorithm of blind equalization on time-variant channels.Computer simulation results have shown that the convergence rate of blind equalization can be greatly improved with this method,and the equalizer can be set up within 200~300 symbols when it becomes divergent on the time-variat channels.
