Distributed Gradient Based Gain Allocation for Coherent Multiuser AF Relaying Networks
—A set of distributed non-cooperating relay antennas is known to be capable of orthogonalizing multiple sourcedestination pairs in space by coherent amplify-and-forward (AF) rela...

A Cluster-Based Multiuser Cooperative Network
Abstract— A novel cluster-based coherent multi-user (MU) relaying system is proposed, where a number of source/destination pairs communicate concurrently over the same physical c...

Impact of CSI on Distributed Space-Time Coding in Wireless Relay Networks
We consider a two-hop wireless network where a transmitter communicates with a receiver via M relays with an amplify-and-forward (AF) protocol. Recent works have shown that sophis...

Multihop-enabled orthogonalization in Distributed MIMO Networks
—It has recently been proposed to orthogonalize the data streams of n interfering source-destination pairs by employing an intermediate stage of non-cooperating coherent amplify-...
