Adaptive semi-blind linear parallel interference cancellation multiuser detection for DS-CDMA systems

Semi-blind multiuser detection for the reverse link of a multi-cell code-division multiple-access (CDMA) system is considered. In such a system, although active users are present in the home cell and neighbouring cells, the base station receiver only knows the signal information of the users in its own cell. Three new adaptive semi-blind linear multiuser detectors are proposed, based on a parallel…
