基于小波变换的线性均衡器及其收敛算法改进

Linear Equalizer Based on Wavelet and Its Algorithm Improvement

对基于正交小波变换的线性均衡器做了研究 ,对传统的 L MS(least mean square)算法做了改进 .在计算机仿真的自适应信道均衡中 ,此法使收敛的速度得到较大的提高 ,明显优于传统的 L MS算法 ,而计算量增加不多 .理论分析与计算机模拟都证实了该算法的优越性 。

In this paper, linear equalizer based on wavelet transform is studied. Improvement to the traditional least meansquare (LMS) algorithm is proposed, leading to considerable increase of convergence speed in computer simulated adaptive channel equalization. It has been shown both theoretically and through computer simulation that the proposed technique outperforms. The LMS algorithm with moderate increase of computation complexity.
