One of the major challenges the mobile broadband community faces is the exponential
increase in mobile data traffic, even more so, for cell‐edge users. Thus, in a multitier …

We consider a K link multiple-input multiple-output (MIMO) interference channel, where each
link consists of two full-duplex (FD) nodes exchanging information simultaneously in a bi …

In this paper, we investigate the problem of spectrum leasing in cognitive radio (CR)
networks, while incorporating two advanced physical-layer technologies, ie, multiple-input …

We study relay selection in both decode-and-forward (DF)-based and amplify-and-forward
(AF)-based cooperative diversity networks consisting of a source, multiple relays, and a …

In this work, we investigate the joint relay and user selection problem in two different multi-
relay multi-user MIMO transmission modes, namely, an existing competition mode and a …

We consider optimal linear precoder and decoder designs in a multi-cell multiple-input
multiple-output system, where base stations and mobile users are both operating in full …

In this paper, we investigate two different relay selection schemes, opportunistic relaying
(OR) and selection cooperation (SC), for decode-and-forward (DF)-based relay networks …

With increasing emphasis on incorporating energy awareness in future communication
systems, it is desirable to explore power-efficient resource allocation techniques. Therefore …

The outage probability of a two-hop coordinated decode-and-forward relay network is
investigated. The case of two interfering cells is considered. This is analogous to the case …

In this paper, precoder designs are proposed for the wireless X networks aided by a relay
and with no or very limited channel state information at the transmitters (CSIT). First, we …
