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,...

Fixed SINR solutions for the MIMO wiretap channel
This paper studies the use of artificial interference in reducing the likelihood that a message transmitted between two multiantenna nodes is intercepted by an undetected eavesdro...

Beamforming design for multi-user two-way relaying with MIMO amplify and forward relays
Relays represent a promising approach to extend the cell coverage, combat the strong shadowing effects as well as guarantee the QoS in dense networks. Among the numerous existing ...

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...

Distributed beamforming and power allocation for cooperative networks
Cooperative diversity systems rely on using relay nodes to relay copies of transmitted information to the destination such that each copy experiences different channel fading, henc...
