Power Efficient Decode-and-Forward Cooperative Relaying [PDF]
IEEE Wireless Communications Letters, 2012 Cooperative communications have been proven to be effective in enhancing performance of wireless networks. In this letter, we introduce and propose adaptive relay-selection rules to offer a tradeoff between fairness and energy consumption at each node for a network with multiple, mutually cooperative nodes.

Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays [PDF]
Journal of Electrical and Computer Engineering Innovations, 2013 In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination.

Full-Duplex Relaying With Quantize-Map-and-Forward
IEEE Access, 2018 The quantize-map-and-forward (QMF) has been recently proved to achieve the capacity of arbitrary networks within a bounded gap and optimal diversity-multiplex tradeoff performance.

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. The problem of

A New Coding Paradigm for the Primitive Relay Channel
Algorithms, 2019 We consider the primitive relay channel, where the source sends a message to the relay and to the destination, and the relay helps the communication by transmitting an additional message to the destination via a separate channel.

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks
Sensors, 2014 In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

Performance Comparison of Relay-Based Covert Communications: DF, CF and AF
Sensors, 2023 In this paper, we investigate the performance of covert communications in different types of a relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and-forward (AF).

An Efficient Partner Selection Method to Overcome the Interference Effect in Wireless Networks
IEEE Access, 2019 In this paper, through a mathematical analysis of the overall links capacity equation, we present an efficient partner selection criterion in a cooperative communication scheme with a time-varying fading channel and severe interference on the cooperative
