Cooperative communications can exploit the distributed spatial diversity-gain to improve the
link performance. In this paper, we investigate the application of adaptive modulation …

Associant des perspectives sémantique et discursive, l'article s' attache à la description et à
la caractérisation des dénominations de groupes sociaux constitués (partis politiques …

Adaptive resource allocation to exploit multiuser diversity and spacial diversity in OFDMA
relay-aided cooperative cellular networks is studied. Assuming that the BS has all the …

In this paper we consider a source, N relays, a destination, a channel realization and a per-
slot global power constraint and we try to resolve the following problem: what is the best way …

This paper discusses on the fair resource allocation in OFDMA two-hop cooperative relaying
cellular networks which consist of a single base station (BS), dedicated fixed relay stations …

This paper addresses a power control and Inter-Cell Interference (ICI) estimation problem in
uplink Single Carrier Frequency Division Multiple Access (SC-FDMA) networks. We consider …

The two main Amplify and Forward cooperative protocols are the orthogonal (OAF) and the
nonorthogonal one (NAF). In this paper, we consider a given source, relays, a destination …

We consider a power allocation problem for three-node cooperative diversity systems using
a relay node. Specifically, we focus on an amplify-and-forward (AF) protocol due to the …

Performance optimization of communication networks with quality of services (QOS)
considerations for all active users is highly desirable. The growth of wireless multimedia …

This paper investigates the power allocation among users for the multi-user superposition
transmission system, where messages from different users are superimposed and mapped …
