本文提出了一种具有分布式处理功能的massive MIMO基站的可扩展模块化体系结构。当每个节点处理所有额外涉及的处理时，可以通过添加新节点来容易地添加新天线。该体系结构支持共轭波束形成、迫零和MMSE，其中对于后两种情况需要中心矩阵求逆。该矩阵求逆所需时间的影响与一般帧格式一起仔细分析。作为贡献的一部分，提出了仔细的计算，内存和通信分析。结果表明，所有计算都可以映射到单个计算结构，由单个这样的处理单元组成的处理节点可以处理宽范围和多个终端。

英文摘要：
In this work, a scalable and modular architecture for massive MIMO base stations with distributed processing is proposed. New antennas can readily be added by adding a new node as each node handles all the additional involved processing. The architecture supports conjugate beamforming, zero-forcing, and MMSE, where for the two latter cases a central matrix inversion is required. The impact of the time required for this matrix inversion is carefully analyzed along with a generic frame format. As part of the contribution, careful computational, memory, and communication analyses are presented. It is shown that all computations can be mapped to a single computational structure and that a processing node consisting of a single such processing element can handle a broad range of bandwidths and number of terminals.
