Cell-Free 大规模 MIMO(Massive Multiple-Input Multiple-Output,Massive MIMO)通过部署成百上千个无线接入点(Access Points,APs),采用时分双工(Time Division Duplexing,TDD)操作模式,利用同一时频资源服务于所有用户(User Equipment,UE),并连接中央处理单元(Central Processing Unit,CPU)进行上下行用户传输和信号处理,...
One of the major technological breakthroughs to cope with these unprecedented demands is the cell-free (CF) massive multiple-input multiple-output (mMIMO) systems. In CF mMIMO, a large number of distributed access points are connected to a central processing unit, and serve a smaller number ...
Cell-free (CF) massive multiple-input multiple-output (MIMO) systems, which exploit many geographically distributed access points to coherently serve user equipment via spatial multiplexing on the same time-frequency resource, has become a vital component of the next-generation mobile communication ...
Cell-free mMIMO systems typically use one of two implementations: centralized or distributed, as illustrated in this figure. In the centralized implementation, the CPU performs physical layer processing while the APs relay signals between the CPU and the UEs. In the distributed implementation, the ...
