Fronthaul-Constrained Cell-Free Massive MIMO With Low Resolution ADCs

In cell-free massive MIMO networks, a large number of distributed access points (APs) provide service to a much smaller number of mobile stations (MSs) over the same time/frequency resources. The key idea is to use a central processing unit (CPU) to manage such a densely populated network of APs. Th...
