摘要
文章研究了MIMO(多输入多输出)系统中的随机波束成形(RBF)算法,仿真结果表明:随着用户数的增加,随机波束成形技术可以用最小的反馈获得相干波束成形情况下的吞吐量,并可获得MIMO系统慢衰落信道中下行链路的多用户分集增益和复用增益。
This paper studies the Random Beam Forming (RBF) algorithm in MIMO systems. The simulation results show that with the increasing number of the users, the RBF technology can be used to obtain from the minimum feedback the same throughput as the coherent beam-forming technology, and also the multi-user diversity gain and multiplexing gain of the downlink in the slow fading channels of the MIMO system.
