Sammanfattning

We consider wireless systems with transmit and receive diversity. For reduction of complexity, we propose to use hybrid selection/maximal-ratio transmission at one link end, choosing L out of N antennas. We analyze the performance of such systems, giving analytical bounds and comparing them with computer simulations. Outage probability, symbol error probability, and capacity are shown. We demonstrate that in typical cases, a small number of used antennas L is sufficient to achieve considerable performance gains. We also analyze the influence of the number of antennas at the other link end, of fading correlation, and of channel estimation errors. The simulation results confirm that the proposed scheme is effective in a variety of environments.
