In this paper, we use joint distributed beamforming and cooperative relaying in cognitive
radio relay networks in an effort to enhance the spectrum efficiency and improve the …

In this work, we design outage constrained collaborative relay beamforming (CRBF) vectors
for a peer-to-peer amplify-and-forward (AF) relay network with imperfect channel state …

We consider in this paper distributed beamforming for two-way cognitive radio networks in
an effort to improve the spectrum efficiency and enhance the performance of the cognitive …

In this paper, we consider multipoint-to-multipoint multi-input multi-output relay systems
where multiple source-destination pairs simultaneously communicate through a single …

This article studies transceiver design methods for multiple-source and multiple-destination
communication systems via an amplify-and-forward relay. Specifically, sum mean-square …

We consider a multipoint-to-multipoint cognitive network wherein the communications from L
sources to their designated destinations are carried out through the use of K relays in a dual …

Multiple antenna source, relay, and destination filter sets are developed that minimize the
sum mean-squared error (MSE). Motivated by the equivalence of the transmit-centric sum …

In this paper, we study the performance of multiple‐input multiple‐output cognitive amplify‐
and‐forward relay networks using orthogonal space–time block coding over independent …

In this paper, we use a distributed beamforming method in cognitive radio relay networks in
an effort to enhance the spectrum efficiency and improve the performance of the cognitive …

This paper is concerned with linear relay and destination filter design methods for the multi-
user peer-to-peer amplify-and-forward relaying systems. Specifically, the relay and …
