Full-Duplex Relaying With Quantize-Map-and-Forward
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
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

Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays [PDF]
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.

A New Coding Paradigm for the Primitive Relay Channel
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
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.

Transmit Signal and Bandwidth Optimization in Multiple-Antenna Relay Channels [PDF]
Transmit signal and bandwidth optimization is considered in multiple-antenna relay channels. Assuming all terminals have channel state information, the cut-set capacity upper bound and decode-and-forward rate under full-duplex relaying are evaluated by ...

Performance Comparison of Relay-Based Covert Communications: DF, CF and AF
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).

On relay selection for decode-and-forward relaying [PDF]
In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source.
