Performance Evaluation of Opportunistic Beamforming with SINR Prediction for HSDPA
— In this paper, Opportunistic Beamforming for HSDPA is considered. Opportunistic Beamforming can jointly increase the system throughput and the quality of service in multiuser communication systems with Proportional-Fair Scheduling, since with this beamforming scheme a user experiences more fading peaks in a given period of time. However, the existence of an SINR feedback delay from the user to the base station degrades the performance in such a system rapidly due to outdated and thus mismatched SINR information. Here, the prediction of the SINR in the base station is proposed with a predictor structure that is matched to the beamforming process.
