一种混和型盲均衡算法
A Mixed Blind Equalization Algorithm

摘要: 盲均衡器在通信系统中有着重要的作用,但一般的盲均衡器存在收敛速度慢的缺点。文中以广泛使用的CMA (Constant Modulus Algorithm)为基础,提出了一种混和型盲均衡算法,不仅提高了收敛速度,而且减小了收敛后的剩余干扰,使均衡器收敛后不必切换到普通均衡方式。Abstract: Blind equalizer plays an important role in communication systems, but most blind equalizers have sa shortage that convergence speed is low.This paper presents a mixed algorithm based on the widely used CMA(Constant Modulus Algorithm).The convergence speed is improved.The residual error is also reduced.Whoasmore the blind equalizer don't have to switch to general equalization mode after convergence.
