Most existing works on orthogonal frequency division multiple access (OFDMA) multihop cellular networks have assumed half-duplex relay, which suffers from spectral inefficiency …
The tremendous successes of wireless communications, including cellular systems, wireless local area networks (WLAN), satellite communications and underwater acoustics (UWA) …
This paper analyzes the capacity of a wireless relay network composed of a large number of nodes that operate in an amplify-and-forward mode and that divide into a fixed number of …
A uniform mobile user quality of service and a distributed use of the spectrum represent the key-ingredients for next generation cellular networks. Toward this end, physical layer …
Multiple-input multiple-output (MIMO) scheme is able to improve the modern communications system performance in terms of increased throughput or reliability. As a …

One of the most important problems of fault-tolerance issues lies in the Byzantine Agreement (BA) problem. In this work, the byzantine problem is re-examined in a virtual backbone of …
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 …
