Performance of Massive MIMO Uplink with Zero-Forcing receivers under Delayed Channels
Anastasios K. Papazafeiropoulos, Hien Quoc Ngo, Tharm Ratnarajah
In this paper, we analyze the performance of the uplink communication of massive multi-cell multiple-input multiple-output (MIMO) systems under the effects of pilot contamination a…
