Achieving "Massive MIMO" Spectral Efficiency with a Not-so-Large Number of Antennas
Channel training downlink scheduling frequency reuse inter-cell cooperation large-system analysis

Abstract: The main focus and contribution of this paper is a novel network-MIMO TDD architecture that achieves spectral efficiencies comparable with "Massive MIMO", with one order of magnitude fewer a...
Abstract: We consider a multicell MIMO uplink channel where each base station (BS) is equipped with a large number of antennas N. Recent work has shown that, as N grows infinitely large, (i) the simpl...
