摘要
在分析小波包和传统自适应线性均衡的基础上 ,提出了一种基于小波包变换的自适应均衡器结构 ,并给出了相应的自适应均衡算法 .与通常的基于小波变换的自适应均衡算法相比 ,该算法利用了小波包对小波空间的进一步划分 ,因此其对信号的去相关能力比小波变换更强 .仿真结果表明了该算法收敛速度较快 ,且计算量增加较少 ,易于实时实现 .
Based on the analysis of wavelet packets and traditional adaptive equalization, an adaptive equalizer structure and its adaptive algorithm, based on wavelet packets transform, are presented. This algorithm makes use of the ability of wavelet packets to divide the wavelet space further, which shows that wavelet packets has a better decorrelation than that of wavelet transform. Also, its realization is easy and its property is analyzed. Finally, simulation shows that its convergence speed is faster and its computation complexity is smaller.
