Description
Summary:In order to improve the throughput of the opportunistic beamforming, a technique enhancing opportunistic beamforming is proposed, which combines the multiple vectors and receive antenna selection technique. Using multiple random weighting vectors at the base station and additional receive antennas at the mobile users can be viewed as increasing the effective number of users on the downlink. Significant performance improvement is achieved especially for small number of users. The simplicity and inexpensive deployment of this technique make it a highly desirable enhancement to opportunistic beamforming.
