Quasi-Concavity for Gaussian Multicast Relay Channels
Entropy, 2019 Standard upper and lower bounds on the capacity of relay channels are cut-set (CS), decode-forward (DF), and quantize-forward (QF) rates. For real additive white Gaussian noise (AWGN) multicast relay channels with one source node and one relay node ...

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

Performance Analysis of Decode-and-Forward Relaying in Gamma-Gamma Fading Channels
IEEE Photonics Technology Letters, 2012 Decode-and-forward (DF) cooperative communication based on free space optical (FSO) links is studied in this letter. We analyze performance of the DF protocol in the FSO links following the Gamma-Gamma distribution.

Covert Communications in a Hybrid DF/AF Relay System [PDF]
SensorsIn this paper, we study covert communications in a hybrid decode-and-forward (DF)/ amplify-and-forward (AF) relay system. The considered relay in normal operation forwards messages from a source node to a destination node in either DF or AF mode on ...

International Journal of Communication Networks and Information Security (IJCNIS), 2022 Decoding high complexity is a major issue to design a decode and forward (DF) relay protocol. Thus, the establishment of low complexity decoding system would beneficial to assist decode and forward relay protocol. This paper reviews existing methods for the min-sum based LDPC decoding system as the low complexity decoding system.

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

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

Cooperative Detection for Primary User in Cognitive Radio Networks
EURASIP Journal on Wireless Communications and Networking, 2009 We propose two novel cooperative detection schemes based on the AF (Amplify and Forward) and DF (Decode and Forward) protocols to achieve spatial diversity gains for cognitive radio networks, which are referred to as the AF-CDS, (AF-based Cooperative ...

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 ...
