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 ...

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.

Entropy, 2017 This paper introduces and studies a model in which two relay channels interfere with each other. Motivated by practical scenarios in heterogeneous wireless access networks, each relay is assumed to be connected to its intended receiver through a digital link with finite capacity.

On the Capacity of a Two-Hop Half-Duplex Relay Channel With a Markovian Constrained Relay
IEEE Access, 2019 Consider a two-hop half-duplex relay channel (source-relay-destination) with a Markovian-constrained relay. The capacity of such channel is shown to be equal to the well-known cut-set upper bound. For the case where the relay-to-destination link is noise-

A Relay Selection Method for Battery-dependent Relay Nodes [PDF]
Jisuanji gongcheng, 2017 Due to the fast power consumption and even the reduction of network lifetime caused by the frequent data forwarding for the battery-dependent relay nodes with higher channel qualities in collaborative communication network,a relay selection method is ...

Modular Algebraic Precoding Relay System Model Based on Lattice Reduction
IEEE Access, 2018 According to the existing multi-antenna relay forwarding protocol, the relay matrix can be split into two parts-relay nodes forward and backward filters direct concatenation, then in actual channel matrix design, relay's forward and backward channel ...
