The transmitter is a multi-antenna base-station broadcasting to users. Each user has multiple antennas at the receiver. The beamforming filter is a group maximum SINR filter which exploits intra-group cooperation, and the power allocated to each data stream is adjusted to enhance performance. Simulation results verify the superiority of the proposed algorithm over previous works. ©2009 IEEE. |
