Performance Analysis of a Dual-Hop Cooperative Relay Network with Co-Channel Interference [PDF]
Radioengineering, 2014 This paper analyzes the performance of a dual-hop amplify-and-forward (AF) cooperative relay network in the presence of direct link between the source and destination and multiple co-channel interferences (CCIs) at the relay.

Joint Channel-Network Coding for the Gaussian Two-Way Two-Relay Network
EURASIP Journal on Wireless Communications and Networking, 2010 New aspects arise when generalizing two-way relay network with one relay to two-way relay network with multiple relays. To study the essential features of the two-way multiple-relay network, we focus on the case of two relays in our work.

Hybrid Protocols for Relay-Assisted Non-Orthogonal Multiple Access in Power Line Communications
IEEE Open Journal of the Communications Society, 2023 We study the outage probability performance of hybrid protocols in relay-assisted, non-orthogonal multiple access (NOMA)-based power line communication. In particular, we consider two networks with source, relay and destination nodes, namely, cooperative

On the Performance Gain of Hybrid Decode-Amplify-Forward Cooperative Communications
EURASIP Journal on Wireless Communications and Networking, 2009 We investigate the performance of adaptive decode-forward (ADF), amplify-forward (AF), and hybrid decode-amplify-forward (HDAF) relaying protocol. Specifically, we derive the closed-form expression of symbol error probability (SEP) for these three ...
