An adaptive RAKE receiver with diversity combining is proposed for a DS-CDMA system in multipath fading channels. The proposed adaptive RAKE receiver exploits antenna diversity and adaptive interference cancellation (AIC) to mitigate the effect of both multipath fading and multiple-access interference (MAI). The LMS algorithm with variable step-size is used to update the tap-weight vector of AICs. The performance of the proposed receiver is evaluated by computer simulation for the various numbers of antennas and RAKE fingers. It is shown that the proposed receiver achieves significant performance improvement over a conventional RAKE receiver
