论文摘要
无细胞的大型MIMO为多个用户提供无处不在的连接，并且使用无线电条纹实施非常有效。本文提出了一个并行的无线电条纹方案，以允许访问点同时进行信号处理。简单的最大比率（MR）处理在此方案中起作用，但其性能不佳。因此，本文进一步提出了两种有效的并行方案，以获得更好的性能。首先是具有量身定制的以用户为中心的策略的干扰意识MR处理。第二个是分布的正则化零效率（D-RZF）算法，该算法源自LMMSE。仿真结果表明，所提出的并行方案的性能比现有作品更好。
Cell-free massive MIMO provides ubiquitous connectivity for multiple users, and implementation using radio stripes is very efficient. This paper proposes a parallel scheme for radio stripes to allow access point to do signal processing simultaneously. Simple maximum ratio (MR) processing works in this scheme, but its performance is bad. Therefore, this paper further proposes two efficient parallel schemes to gain better performance. The first is interference-aware MR processing with a tailored user-centric strategy. The second is distributed regularized zero-forcing (D-RZF) algorithm which derives from LMMSE. Simulation results show that the proposed parallel schemes gain better performance than existing works.
