摘要：
We consider a multi-user (MU) multiple-input multiple-output (MIMO) channel where each node is equipped with multiple antennas. An orthogonal projection optimization (OPO) algorithm is proposed based on linear transmit beam-forming and receive combining. The performance of the OPO algorithm is analyzed which discloses its convergence characteristics. The complexity of the OPO algorithm is also addressed and a computationally efficient algorithm is developed. The OPO algorithm is applied to both uplink and downlink MU MIMO systems, and simulation results show its excellent performance.
