Abstract :
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.
