一种低复杂度非满秩正交随机波束成型传输方法

Low-complexity Deficient-rank Orthogonal Random Beamforming Algorithm

与现有研究点对点的无线通信手段不同,基于网络整体架构,分析SINR、波束矢量、用户数、吞吐量内在关联,发掘网络内部多用户空间分布不一致性带来的用户间的分集增益,提升系统的吞吐量。将随机波束成型与迫零算法有机结合,研究一种新型非满秩正交波束成型算法,克服了满秩波束间的相互干扰,提升系统容量;最后对性能作了详细分析与验证,得出几个极有意义的结论。

This paper achieved the user diversity by analying the relationship among the SINR, beamforming, user number and throughout, which is different with the traditional P2P communication. The deficient-rank ORBF algorithm, which we proposed can improve the throughput greatly, because the algorithm reduces the multi-beam interference and promotes the throughput. The simulation results are given at the end of paper.
