Multi-User MIMO with outdated CSI: Training, Feedback and Scheduling
Ansuman Adhikary, Haralabos C. Papadopoulos, Sean A. Ramprashad +1
Conventional MU-MIMO techniques, e.g. Linear Zero-Forced Beamforming (LZFB), require sufficiently accurate channel state information at the transmitter (CSIT) in order to realize s…

Achieving "Massive MIMO" Spectral Efficiency with a Not-so-Large Number of Antennas
Hoon Huh, Giuseppe Caire, Haralabos C. Papadopoulos +1
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 magnitu…

Joint Scheduling and ARQ for MU-MIMO Downlink in the Presence of Inter-Cell Interference
Hooman Shirani-Mehr, Haralabos C. Papadopoulos, Sean A. Ramprashad +1
User scheduling and multiuser multi-antenna (MU-MIMO) transmission are at the core of high rate data-oriented downlink schemes of the next-generation of cellular systems (e.g., LTE…
