Abstract

Multi-user detection is a paradigm that is used to enhance the performance of the receivers in cellular networks in terms of Bit Error Rate (BER), capacity and near-far effect. Parallel Interference Cancellation is the choice for most current multi-user detection receivers because of its simplicity in implementation and good qualitative parameters. Decorrelator-based Parallel Interference Cancellation (PIC) has been proposed to improve the performance of the PIC receiver. In this paper, we make an important observation about the determination of the Decorrelator that makes it feasible for it to be used in conjunction with PIC in the base-station receiver.
