Abstract :
In this paper we examine a space-time multiuser receiver with two parallel interference cancellation (PIC) stages for the uplink in the UMTS-FDD mode. The structure has a performance which is better than the one of the maximum-ratio combiner (MRC) and can reach the single-user performance under the assumption of perfect channel knowledge. Even with channel estimation the proposed receiver achieves a very good performance while maintaining low complexity
