Abstract

A blind adaptive step-size time-domain receiver for multi-carrier code-division multiple access (MC-CDMA) systems is presented. Adjustment rules for the receiver tap-weight as well as its step-size are based upon the stochastic approximation of the constant modulus (CM) criterion. The ability of the proposed receiver to detect the desired user in multipath fading channels at full load is assessed. Sensitivity to the various initial values of the step-size and the adaptation rates of the algorithm is also investigated.
