多入多出(MIMO)系统可以获得比单发单收系统更高的容量,对于MIMO系统,最大似然检测是最优接收,但其
指数复杂度难以在实际中应用。针对该问题,结合格缩减理论提出了基于Householder变换的复数域格缩减算法,将该算法和
MIMO次优检测算法相结合,给出了量化判决方法,且该复数域格缩减算法复杂度小于实数域格缩减算法。仿真结果表明,
基于Householder变换复数域格缩减的MIMO次优检测算法,通过优化信道矩阵可以得到更好的判决域,取得了逼近最优最大
似然检测算法的性能。

本文考虑了一种新的系统模型,它结合了通用收发器硬件损伤在BSs(配备大型天线阵列)和单天线用户设备(UE)。与传统硬件的传统情况相反,我们表明硬件损伤在信道估计精度和每个UE的下行链路/上行链路容量上创建有限天花板。令人惊讶的是,容量主要受限于UE的硬件,而大规模阵列中的损伤的影响逐渐消失,并且用户间干扰(特别是导频污染)变得可以忽略不计。此外,我们证明了大量的MIMO所提供的巨大自由度可以用来减少发射功率和/或容忍较大的硬件损伤,这允许使用廉价和节能的天线元件。(This paper cons
