摘要：
The inclusion of groupwise interference cancellation (IC) techniques into WCDMA uplink receivers is studied in this paper. Emerging third generation WCDMA signal structures for multirate transmission are utilized dong with necessary uplink techniques, namely antenna diversity reception, transmitter power control and signal-to-interference ratio (SIR) estimation. A groupwise serial interference cancellation (GSIC) technique suitable for WCDMA systems using long spreading sequences is presented along with the necessary estimation techniques. A simple intercell-interference (ICI) model is incorporated and the behavior of the receiver in a power controlled environment is studied.
