摘要

A variable step size technique is applied to joint Modified Constant Modulus Algorithm (MCMA) and Decision-Directed (DD) equalization algorithm to speed up convergence with respect to the original algorithm. The same technique is used with joint CMA and DD algorithm and exhibits improved performance.
