Compress-and-Forward for Relay Broadcast Channels without Common Messages [PDF]

Cybernetics and Information Technologies, 2015
This paper is connected with compress-and-forward strategy for two-user relay broadcast channels without common messages, where the relay node has private messages from the source, in addition to aiding traditional communication from the source to the ...

Covert communications in a compress-and-forward relay system

ICT Express
In this paper, we study covert communications strategies in a compress-and-forward (CF) relay system. Along with a public message to a destination node via a CF relay, a source node attempts to transmit a covert message while evading the surveillance of ...

Generalized Compute-Compress-and-Forward [PDF]

IEEE Transactions on Information Theory, 2019
Compute-and-forward (CF) harnesses interference in wireless communications by exploiting structured coding. The key idea of CF is to compute integer combinations of codewords from multiple source nodes, rather than to decode individual codewords by treating others as noise.

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).

Compress-and-Forward Via Multilevel Coding and Trellis Coded Quantization

IEEE Communications Letters, 2021
Compress-forward (CF) relays can improve communication rates even when the relay cannot decode the source signal. Efficient implementation of CF is a topic of contemporary interest, in part because of its potential impact on wireless technologies such as cloud-RAN.

End-to-End Joint Antenna Selection Strategy and Distributed Compress and Forward Strategy for Relay Channels

EURASIP Journal on Wireless Communications and Networking, 2009
Multihop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time codes were proposed to maximize the achievable diversity-multiplexing ...

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 ...
