The non-linear LMS algorithm is obtained by introducing the non-linearity into the typical LMS algorithm.The cost function is built according to LMS algorithm,the blind separation algorithm is induced,and the induction procession is given in case of real number and complex number respectively.The result indicates that the algorithm is the same to both maximum entropy and minimum mutual information(ACY) algorithms.The relation between ACY algorithms and LMS algorithms was proved.And the complex ACY algorithm was found out.The performance of proposed algorithms is verified by computer simulation whose results are shown in the paper.
