Iterative Slepian-Wolf Decoding and FEC Decoding for Compress-and-Forward Systems [PDF]
2012 IEEE Vehicular Technology Conference (VTC Fall), 2012 While many studies have concentrated on providing theoretical analysis for the relay assisted compress-and-forward systems little effort has yet been made to the construction and evaluation of a practical system. In this paper a practical CF system incorporating an error-resilient multilevel Slepian-Wolf decoder is introduced and a novel iterative ...

Sequential slotted amplify-decode-and-forward [PDF]
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013 In this paper, we propose a novel slotted hybrid cooperative protocol named the sequential slotted amplify-decode-and-forward (SADF) protocol and evaluate its performance in terms of diversity-multiplexing trade-off (DMT). The relays between the source and destination are divided into two different groups and each relay either amplifies or decodes the ...

Lattice decoding for the Compute-and-Forward protocol [PDF]
Third International Conference on Communications and Networking, 2012 In this work we focus exclusively on the Compute-and-Forward (C&F) protocol as a channel coding-based approach for Physical Layer Network Coding. The Core principle of this relaying strategy is based on using Nested Lattice Codes. The source nodes in a relay network encode their messages into lattice codewords and transmit them to the relay. The latter

Multilevel Coding for the Full-Duplex Decode-Compress-Forward Relay Channel
Entropy, 2017 The Decode-Compress-Forward (DCF) is a generalization of Decode-Forward (DF) and Compress-Forward (CF). This paper investigates conditions under which DCF offers gains over DF and CF, addresses the problem of coded modulation for DCF, and evaluates the ...

Functional-Decode-Forward for the General Discrete Memoryless Two-Way Relay Channel [PDF]
, 2010 We consider the general discrete memoryless two-way relay channel, where two users exchange messages via a relay, and propose two functional-decode-forward coding strategies for this channel.

Delay-universal decode-and-forward relaying
2011 Australian Communications Theory Workshop, 2011 We study delay-universal sequential streaming over discrete memoryless three-terminal relay networks, and propose a decode-and-forward relaying scheme. We derive upper bounds on the error performance of the proposed system, which assists in system design and analysis.

On the Equal-Rate Capacity of the AWGN Multiway Relay Channel [PDF]
, 2012 The L-user additive white Gaussian noise multiway relay channel is investigated, where L users exchange information at the same rate through a single relay. A new achievable rate region, based on the functional-decode-forward coding strategy, is derived.

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.

International Journal of Electrical and Computer Engineering (IJECE), 2020 The deficiencies of regular cooperative relaying schemes were the main reason behind the development of Incremental Relaying (IR). Fixed relaying is one of the regular cooperative relaying schemes and it relies on using the relay node to help in ...

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.
