This paper provides a comprehensive scaling law-based performance analysis for multicell multiuser massive multiple-input-multiple-output (MIMO) downlink systems. Imperfect channel state information (CSI), pilot contamination, and channel spatial correlation are all considered. First, a sum-rate lower bound is derived by exploiting the asymptotically deterministic property of the received signal power,...
This work provides a comprehensive scaling law based performance analysis for single-cell multi-user massive multiple-input-multiple-output (MIMO) downlink systems with maximal-ratio transmission (MRT). Channel state information (CSI) error and channel spatial correlation are both considered. First, a sum-rate lower bound is derived by using Jensen's inequality and the asymptotically deterministic...
