We consider wireless systems with maximal-to the different transmit antennas are weighted replicas of ratio combining diversity at the base station, and hybrid selection/maximal ratio combining at the mobile station. We have recently proposed these systems, which provide high-quality data links, while keeping the complexity at the mobile station low. We analyze their performance in various realistic scenarios. Specifically, we analyze the influence of the number of base station antennas, of fading correlation and channel estimation errors. Furthermore, we explore the performance in channels measured in a microcellular environment. The simulation results confirm that the proposed scheme is effective in a variety of environments.
