Performance Analysis of 3D Massive MIMO Cellular Systems with Collaborative Base Station
Published 2014-01-01“…Utilizing this bound, we pursue a “large-system” analysis and provide the asymptotic expression when the number of antennas at the BS grows large, and when the numbers of antennas at transceiver grow large with a fixed ratio. We demonstrate that the lower bound is very tight and becomes exact in the massive MIMO system limits. …”
