Exploiting Multi-Antennas for Opportunistic Spectrum Sharing in Cognitive Radio Networks
—In cognitive radio (CR) networks, there are scenarios where the secondary (lower priority) users intend to communicate with each other by opportunistically utilizing the transmi...

On the Achievable Throughput of MIMO Broadcast Channels with Finite Rate Feedback
Abstract— We consider multiuser scheduling with limited feedback of partial channel state information in MIMO broadcast channels. By using spatial multiplexing at the base statio...

Beam Selection Strategies for Orthogonal Random Beamforming in Sparse Networks
Abstract--Orthogonal random beamforming (ORB) constitutes a mean to exploit spatial multiplexing and multi-user diversity (MUD) gains in multi-antenna broadcast channels. To do so,...

Adaptive Modulation and Coding for Bit Interleaved Coded Multiple Beamforming
— Bit interleaved coded multiple beamforming (BICMB) was previously designed to achieve full spatial multiplexing of min(N, M) and full spatial diversity of NM for N transmit and...

Downlink Limited Feedback Transmission Schemes for Asymmetric MIMO Channels
Abstract—In multiple-input multiple-output (MIMO) broadcast channels, multiuser diversity is exploited by scheduling data transmission to users with best channel conditions. To ï...
