Multisensor partial parallel interference cancellation for UMTS uplink

Partial parallel interference cancellation (PPIC) for CDMA mobile communication is known as a powerful method. In this paper, after a brief look at PPIC, a multisensor version of the approach is studied under the UMTS uplink parameters. The performance is evaluated by considering a multipath fading environment and the effect of channel estimation in the receiver. The results are compared with standard RAKE receiver and the differences show a promising gain.
