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,本文以广泛使用的CMA(ConstantModulusAlgorithm)为基础,提出一种混合型均衡算法,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。 Blind equlizer play import role in communication systems, but most blind equlizers converge too low. This paper present a new mixed alogrithm on which CMA- Constant Modulus Alogrithm is based on, it not ouly improve convergence rate bu also reduce residual distortion , this means that blind equlizer has not to switch to general equlization mode after convergence.
