A relay cooperation scheme is proposed for the downlink of multicell multiple-input-multiple-
output cellular networks. The relay stations (RSs) will cooperatively transmit the signal …

The impact of cognitive radio techniques on the energy efficiency of a downlink cellular
system in which multiple relays assist the transmission of the base station toward multiple …

A study of the effects of co-channel interference on a multirelay system with decode-and-
forward (DF) protocol is presented. Orthogonal relaying is considered, and all relays that …

This paper considers a wireless cooperative cellular data network with a base station and
many subscribers in which the subscribers have the ability to relay information for each other …

In this paper, we consider multiuser cooperative multiplexing schemes in cellular networks
with fixed relays and address the problem of inter-user interference. We propose two …

Wireless relays extend coverage, improve spectral efficiency, and enhance reliability and
rates of wireless cellular communication systems. In this work, we introduce the fundamental …

In this paper, we consider the amplify-and-forward relaying transmission in the downlink of a
multi-channel cellular network with one base station and multiple relay-destination pairs …

This paper presents a comparison and analysis of selection relaying with transmit
beamforming as an effective approach to combat channel impairments in relay-assisted …

In cellular networks, base stations can cooperate in order to bring spatial diversity.
Cooperative diversity enables to increase link capacity and signal to noise ratio. This paper …

The authors investigate the relay‐aided multicell multiple‐input–multiple‐output (MIMO)
cellular network by comparing both the signal forwarding and interference forwarding …
