摘要翻译：
我们考虑了协作无线接入网体系结构，特别是分布式massive MIMO和Cloud RAN的异同。我们特别讨论了将分布式接入点连接到中央处理单元的高容量fronthaul网络的实现对两个方面提出的主要挑战，并考虑了为了限制fronthaul负载而对接收信号的量化对上行链路性能的影响。我们使用Bussgang分解和一种新的信道和数据MMSE估计方法，为我们的分析提供了基础。

英文摘要：
We consider cooperative radio access network architectures, especially distributed massive MIMO and Cloud RAN, considering their similarities and differences. We address in particular the major challenge posed to both by the implementation of a high capacity fronthaul network to link the distributed access points to the central processing unit, and consider the effect on uplink performance of quantization of received signals in order to limit fronthaul load. We use the Bussgang decomposition along with a new approach to MMSE estimation of both channel and data to provide the basis of our analysis.
