Abstract

The capacity of cellular system is limited by two different phenomena namely, multipath fading and Multiple Access Interference (MAI). A beamformer-Rake receiver is a computationally feasible solution to allow temporal-spatial signal processing for effectively overcoming signal fading and MAI. In this paper, the performance of PSA beamformer-Rake receivers in the Geometrically Based Single Bounce (GBSB) circular channel with the uplink W-CDMA signal standard has been investigated. The Least Mean Square (LMS) and the Recursive Least Square (RLS) as PSA-based beamforming techniques have been considered. Maximal Ratio Combining (MRC) coherent RAKE receiver with different number of fingers is considered for simulation. The performances of the aforementioned two PSA-based beamforming techniques are compared in terms of BER against number of users in the following scenarios: antenna elements, RAKE fingers, and beamforming algorithms. ©2008 IEEE.
