This letter advocates the performance of a multiuser relay network (MRN) equipped with a
single amplify-and-forward (AaF) relay over Rayleigh fading environments. We derive new …

In this paper, we investigate the impact of channel side information (CSI) availability at the
source node on the capacity of multi-hop fading relay channels where the nodes are all …

In wireless relay networks, the use of multiple antennas at both the source and destination
can increase the capacity linearly with the number of antennas. In this paper, we investigate …

In this paper, we analyze the diversity order of opportunistic scheduling networks with
arbitrary numbers of relays and users. We show that the opportunistic selection of the relay …

We design user-assisted relaying strategies and analyze their performance in a multiple-
input-multiple-output uplink cellular network. In user-assisted relaying, the base station …

The joint optimization of cooperative relays in a multiple-input multiple-output (MIMO)
multiple relay aided communication system is discussed in this article. A simple linear …

We consider a wireless relay network where two pairs of nodes exchange information with
their partners through a single amplify-and-forward two-way relay with each node equipped …

We propose new low complexity opportunistic relaying strategies for multiple-antenna relay
networks. Assuming that a source communicates with a destination, both equipped with M …

This paper advocates the performance of wireless multiuser relay networks (MRNs)
equipped with a single amplify-and-forward (AaF) relay. For such networks, we focus on …
