One of the key technologies in next generation systems for achieving high throughput and
providing better coverage is relaying. Relaying has attracted a high level of recent research …

In this paper, we consider a parallel relay network where two relays cooperatively help a
source transmit its message to a destination. We assume the source and the destination …

In this paper, protocols for the half-duplex relay channel are introduced and performance
limits are analyzed. Relay nodes underly an orthogonality constraint, which prohibits …

Gastpar and Vetterli named the adhoc networks with one randomly selected source-
destination pair as relay networks and they suggested using arbitrary network coding in …

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 …

Résumé Une qualité de service uniforme pour les utilisateurs mobiles et une utilisation
distribuée du spectre représentent les ingrédients clés des réseaux cellulaires de prochaine …

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 …
