The Arbitrarily Varying Relay Channel [PDF]
Entropy, 2019 We study the arbitrarily varying relay channel, which models communication with relaying in the presence of an active adversary. We establish the cutset bound and partial decode-forward bound on the random code capacity.

Feedback Approach for the Relay Channel with Noisy Feedback and Its Security Analysis [PDF]
EntropyRelay channels capture the essence of several important communication scenarios such as sensor network and satellite communication. In this paper, first, we propose an efficient coding scheme for an additive white Gaussian noise (AWGN) relay channel in ...

Spectral Efficiency of Wireless Relay Network in Frequency Non-Selective Channel
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. A wireless communication system based on a relay network where a link between a source and a destination is carried out through a network of relay nodes have been considered.

On the capacity of the noncausal relay channel [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 This paper studies the noncausal relay channel, also known as the relay channel with unlimited lookahead, introduced by El Gamal, Hassanpour, and Mammen. Unlike the standard relay channel model, where the relay encodes its signal based on the previous received output symbols, the relay in the noncausal relay channel encodes its signal as a function of ...

A simple Encoding Scheme to Achieve the Capacity of Half-Duplex Relay Channel
Advances in Electrical and Electronic Engineering, 2022 In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even though this channel model is widely studied, the capacity is not yet fully understood and particularly has not been tightly expressed.

Relay Channels with Unreliable Helpers
2023 IEEE International Symposium on Information Theory (ISIT), 2023 The relay channel with unreliable helper is introduced and studied. The model is that of a classical relay channel where the input from the relay to the channel has an extra primitive link whose presence is not assured a priori. The extra link represents a helper who may decide not to cooperate in transmission.

Compound relay channel with informed relay and destination [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 A two-state compound relay channel is considered where the relay and the destination are informed about the channel state while the source is not. Achievable rates and upper bounds are derived for discrete memoryless and Gaussian models, and specialized to a scenario with orthogonal components.
