Cell-Free Massive MIMO中没有小区,所有服务天线一致地为所有用户终端服务。 Cell-Free Massive MIMO目前只是一个新概念;它是MIMO与协作多点联合处理(Comp)的新实用且可扩展的版本。在某种程度上是基于良好传播和信道化化特性Massive MIMO技术的新应用。
因为CFmMIMO的天线分布在一个地理区域内,相比较colocated mMIMO遭受不良链路UE的影响更小,因此可以有更高的覆盖概率以及更低的训练时间。 5 Conclusion 本文提出了一个最新的方案使用CFmMIMO作为未来无线网络的解决方案来支持多FL集群,使用连续凸逼近技术,成功提出了一个算法来分配功率和处理频率来尽可能减少每次FL迭代...

We consider the downlink of Cell-Free Massive MIMO systems, where a very large number of distributed access points (APs) simultaneously serve a much smaller number of users. Each AP uses local channel estimates obtained from received uplink pilots and applies conjugate beamforming to transmit data...

A Cell-Free Massive MIMO (multiple-input multiple-output) system comprises a very large number of distributed access points (APs)which simultaneously serve a much smaller number of users over the same time/frequency resources based on directly measured channel characteristics. The APs and users have...
