Optimal Routing for the Gaussian Multiple-Relay Channel with Decode-and-Forward [PDF]
, 2007 In this paper, we study a routing problem on the Gaussian multiple relay channel, in which nodes employ a decode-and-forward coding strategy. We are interested in routes for the information flow through the relays that achieve the highest DF rate.

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

Combining Decoded-and-Forwarded Signals in Gaussian Cooperative Channels [PDF]
2006 IEEE International Symposium on Signal Processing and Information Technology, 2006 The goal of this paper is to investigate different ways of combining signals that have been decoded- nd-forwarded by a bunch of relays. We more deeply look at the case where the relays are in bad reception conditions and the cooperation powers are sufficiently high.
