摘要
本文提出一种基于正交小波的线性均衡算法，用一组规范正交小波及其对应的系数来表示均衡器.在此基础上，提出基于正交小波的判决反馈均衡算法.文中给出了自适应算法，并对算法性能做了分析.采用这种结构的均衡算法，比传统的基于LMS算法的线性均衡器和判决反馈均衡器收敛速度快，误码性能相同，而计算量增加不多.计算机模拟也证实了上述结论.
In this paper, two equlizer structures based on orthogonal wavelets bases are presented, named wavelet based linear equalizer(WBLE) and decision feedback equalizer(WBDFE). The equalizer is represented by a set of orthogonal wavelets and the corresponding corresponding. The peper also gives the adaption algorithm. Theoretical analysis shows that the WBLE and WBDFE converge faster than the conventional FIR LMS based linear equalizer and decision feedback equalizer, while the increase in the computational complexity is very slow.
