标题： Cell-Free Massive MIMO With Radio Stripes and Sequential Uplink Processing

摘要： 无蜂窝大规模MIMO（mMIMO）被设想为一种超越5G的下一代技术，与传统MIMO技术相比，其具有高频谱效率和优越的空间多样性。 主要原理是许多分布式接入点（APs）协作，同时为网络中的所有用户提供服务，而不会创建小区边界。 本文考虑了利用无线电条带网络架构的无蜂窝mMIMO系统的上行链路。 我们提出了一种新颖的顺序处理算法，在每个阶段采用归一化线性最小均方误差（N-LMMSE）合并。 该算法在无蜂窝MMO中实现了干扰抑制，同时保持成本和前传需求较低。 计算和分析了所提算法的频谱效率。 我们得出结论，它在低前传需求和高频谱效率之间提供了有吸引力的权衡。 显示英文摘要

摘要： Cell-free Massive MIMO (mMIMO) is envisaged to be a next-generation technology beyond 5G with its high spectral efficiency and superior spatial diversity as compared to that of conventional MIMO technology. The main principle is that many distributed access points (APs) cooperate to simultaneously serve all the users within the network without creating cell boundaries. This paper considers the uplink of a cell-free mMIMO system utilizing the radio stripe network architecture. We propose a novel sequential processing algorithm with normalized linear minimum mean square error (N-LMMSE) combining at every. This algorithm enables interference suppression in cell-free MMO while keeping the cost and front-haul requirements low. The spectral efficiency of the proposed algorithm is computed and analyzed. We conclude that it provides an attractive trade-off between low front-haul requirements and high spectral efficiency.
