| 摘 要： | 为了提高多用户MIMO系统下行信道的总速率,提出一种基于正交随机波束形成的多权重矩阵选择算法.在每个时隙中,该算法利用多个权重矩阵生成随机波束,基站利用部分信道信息反馈,依据总速率最大的原则选择本时隙的最优权重矩阵并进行数据发送.该算法可以显著提高多用户MIMO系统的总速率,仿真结果也证明了该算法的有效性. |

| Abstract: | In this paper,a multiple weighting matrices selection Strategy for orthogonal random beamforming is discussed to increase the throughput of the multi-user MIMO systems.Multiple weighting matrices are performed and computed during the mini-slots.And the base station selects the best matrix based on the partial channel state information and performs the orthogonal random beamforming during the time slot.The proposed scheme over multi-user random beamforming can increase the throughput of multi-user MIMO syste... |
