摘要：
A blind adaptive step-size, averaging blind sign algorithm (AS-asign) for,suppression of multiple access interference. (MAI) in direct-sequence/code-division multiple access (DS/CDMA) systems is proposed. It combines the sign-regressor algorithm and the concept of variable step-size, uses a second least mean square algorithm for the step size of blind averaging sign-regressor algorithm. Simulations indicate that this algorithm yields improvements over similar adaptive step-size algorithm in dynamic environments.
