In this paper, we present a system model for multiuser multicode code-division multiple access (CDMA) in a multipath fading channel and propose a hybrid receiver scheme for the system. Conventional receivers for CDMA systems utilized interference cancellation (IC) schemes, with the RAKE receiver as an initial data estimator. However, the RAKE receiver generates inaccurate data estimates due the interference...
In this paper, we present a hybrid receiver scheme to overcome the shortcoming of the conventional interference cancellation (IC) receiver, for multiuser multicode CDMA (M-CDMA) systems. In conventional IC receivers, RAKE receiver is used in the first stage to obtain initial data estimation but substantial interference at the output of the RAKE receiver renders the initial data estimation highly inaccurate...
