摘要: 基于数据重用的CMA算法可以用来解决短突发信号的盲均衡问题,但是其收敛成因却鲜有研究。通过经典CMA算法的推导,引出基于数据重用的CMA盲均衡算法,对其收敛成因进行详细的描述和分析,给出相应的结论,通过计算机仿真验证了这些分析和结论的有效性。

Abstract: The data-reusing constant modulus algorithm can be used to solve the problem of blind equalization of short burst signals, but its convergent origin has no more study. This paper introduces the data-reusing CMA after the classical CMA. Its convergent origin is described and analysed, and the corresponding results are given. The validity of these analyses is proved by computer simulation.
