In this thesis new techniques are presented to achieve performance enhancement in
wireless cooperative networks. In particular, techniques to improve transmission rate and …

Cooperative technology constitutes a breakthrough in the design of wireless communication
systems. This is due to its relatively simple implementation and its significant performance …

The Gaussian two-way relay channel and the Gaussian two-way diamond channel are
studied. First, we derive an analytical expression for the outer bound to the capacity region …

The fields of channel coding, source coding and information theory were founded by Claude
Shannon in his most celebrated 1948 paper,“A Mathematical Theory of Communication”[1] …

In this paper, the diamond relay channel is considered, which consists of one source-
destination pair and two relay nodes connected with rate-limited out-of-band conferencing …

In this paper, the diamond relay channel is considered, which consists of one source-
destination pair and two relay nodes connected with rate-limited out-of-band conferencing …

The cooperative relaying technique has gained a lot of research interest recently. It can
obtain the spatial diversity and improve the system performance as the multiple-input …

Varying channel conditions and interference are inherent in wireless communication
systems and can severely degrade communication rates. Cooperation via relaying, on the …

To meet the rapid growth of wireless applications and multimedia services, the development
of wireless communications that is able to provide higher data rates and more reliable …

In this dissertation we consider cooperative communication systems with relay conferencing,
where the relays own the capabilities to talk to their counterparts via either wired or wireless …
