摘要：
We propose an enhancement of opportunistic beamforming (OBF) to improve the system's overall throughput over time-correlated fading channels. By saving at the base station (BS) the sequence of antenna gains and corresponding SNRs for each user, the proposed system can adopt for the selected user the most appropriate antenna gain from the memory, rather than the current gain, as in the original OBF approach. Computer simulation results for the Jakes-correlated fading channels indicate a favorable throughput performance. Moreover, the proposed scheme can be easily combined with previous enhancements of OBF, yielding further performance improvements.
