基于规范正交小波的自适应均衡器
A NEW KIND OF EQUALIZER BASED ON ORTHONORMAL WAVELETS
-
摘要: 本文在分析传统均衡器性能的基础上,提出了一种基于小波分析的均衡器OWBE,用一组规范正交小波及其对应的一组系数来表示均衡器。文中给出了自适应算法,并对算法性能做了简要分析.与基于LMS算法的横向均衡器(LTE)相比,OWBE收敛速度快,而计算量增加很少,易于实时实现.

Abstract: An orthonormal wavelets based equalizer (OWBE) is presented. The equalizer is represented by a set of orthonormal wavelets and the corresponding coefficients. The paper gives the structure and also the adaption algorithm of the OWBE. Theoretical analysis show that the OWBE convergences faster than the conventional FIR LMS based equalizer (LTE), while the increase in the computational complexity is very little. Several simulations are performed to evaluate the behavior of the OWBE. -
