ملخص: 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.
