Multiuser Diversity with Imperfect Channel Quality Feedback in MIMO Broadcast Networks
—In this paper, we analyze the impact of imperfect channel quality feedback on the scheduling algorithms that exploit multi-user diversity. We consider a time-slotted MIMO broadc...

Opportunistic Feedback Protocol for Achieving Sum-Capacity of the MIMO Broadcast Channel
—This paper presents an opportunistic feedback (OF) protocol that achieves the asymptotic sum-capacity of the fading broadcast channel (BC) with a limited amount of feedback. The...

Feedback reduction in MIMO broadcast channels with LMMSE receivers
In this paper we analyze the performance of random beamforming schemes in a multi-user Gaussian broadcast channel. Each user will have N > 1 receive antennas allowing optimal c...
