Abstract

This paper analyzes the performance of multiuser optimum combining (OC) systems where the desired user undergoes Rician fading, and the received signals are corrupted by Rayleigh-faded interference and noise. We consider the SER and ergodic capacity in asymptotic SNR regimes, and derive new closed-form expressions for key performance parameters such as the diversity order, array gain, and wideband slope. These results clearly reveal the impact of the Rician if-factor, which is shown to be advantageous to performance in all cases.
