Combining coded signals with arbitrary modulations in orthogonal relay channels [PDF]
, 2008 We consider a relay channel for which the following assumptions are made. (1) The source-destination and relay-destination channels are orthogonal (frequency division relay channel). (2) The relay implements the decode-and-forward protocol.

Joint Beamforming Optimization and Power Control for Full-Duplex MIMO Two-Way Relay Channel [PDF]
IEEE Transactions on Signal Processing, 2014 In this paper, we explore the use of full-duplex radio to improve the spectrum efficiency in a two-way relay channel where two sources exchange information through an multi-antenna relay, and all nodes work in the full-duplex mode.

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 ...

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-

Incremental Relaying for the Gaussian Interference Channel with a Degraded Broadcasting Relay [PDF]
, 2011 This paper studies incremental relay strategies for a two-user Gaussian relay-interference channel with an in-band-reception and out-of-band-transmission relay, where the link between the relay and the two receivers is modelled as a degraded broadcast ...

“The Capacity of the Relay Channel”: Solution to Cover’s Problem in the Gaussian Case
IEEE Transactions on Information Theory, 2017 Consider a memoryless relay channel, where the relay is connected to the destination with an isolated bit pipe of capacity $C_{0}$ . Let $C(C_{0})$ denote the capacity of this channel as a function of $C_{0}$ . What is the critical value of $C_{0}$ ,
