Multi-User MIMO with outdated CSI: Training, Feedback and Scheduling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…
