Reduced feedback schemes using random beamforming in MIMO broadcast channels
A random beamforming scheme for the Gaussian MIMO broadcast channel with channel quality feedback is investigated and extended. Considering the case where the receivers each have r...

Weighted Sum Rate Optimization for Cognitive Radio MIMO Broadcast Channels
In this paper, we consider a cognitive radio (CR) network in which the unlicensed (secondary) users are allowed to concurrently access the spectrum allocated to the licensed (prim...

MIMO Broadcast Channels with Channel Estimation
— We consider a multi-user MIMO downlink where the transmitter has only estimates of the channel while the receivers have perfect channel information. The impact of channel estim...

Dynamic Channel Feedback Control for Limited-Feedback Multi-User MIMO Systems
—Efficient channel feedback methods are becoming more important in limited-feedback multi-user multiple input multiple output (MU-MIMO) systems. We propose a new Dynamic channEl...

An Achievable Rate Region for the Broadcast Channel with Feedback
A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with noiseless or noisy feedback. The coding strategy involves block-...
