Quasi-Concavity for Gaussian Multicast Relay Channels [PDF]
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 ...

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 ...

Full-Duplex Mode in Amplify-and-Forward Relay Channels: Outage Probability and Ergodic Capacity
International Journal of Antennas and Propagation, 2014 This paper investigates the outage probability and ergodic capacity performances for full-duplex mode in two-way amplify-and-forward relay channels. The two-way relay channels which consist of two source nodes and a single relay node working in full ...

Autoencoder-based Semantic Communication Systems with Relay Channels [PDF]
2022 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 In this paper, we propose a semantic communication scheme for wireless relay channels based on Autoencoder, named AESC, which encodes and decodes sentences from the seman-tic dimension. The Autoencoder module is trained separately and acts as the channel

Beamforming for Simultaneous Wireless Information and Power Transfer in Two-Way Relay Channels [PDF]
IEEE Access, 2016 This paper studies the beamforming designs for simultaneous wireless information and power transfer systems in two-way relaying (TWR) channels. The system consists of two energy-constrained source nodes which employ the power splitting (PS) to receive ...

Throughput Maximization for Two-Way Relay Channels With Energy Harvesting Nodes: The Impact of Relaying Strategies [PDF]
IEEE Transactions on Communications, 2015 In this paper, we study the two-way relay channel with energy harvesting nodes. In particular, we find transmission policies that maximize the sum-throughput for two-way relay channels when the relay does not employ a data buffer.

Secrecy Capacity of a Class of Orthogonal Relay Eavesdropper Channels
EURASIP Journal on Wireless Communications and Networking, 2009 The secrecy capacity of relay channels with orthogonal components is studied in the presence of an additional passive eavesdropper node. The relay and destination receive signals from the source on two orthogonal channels such that the destination also ...

Relay Selection with Network Coding in Two-Way Relay Channels [PDF]
, 2010 In this paper, we consider the design of joint network coding (NC)and relay selection (RS) in two-way relay channels. In the proposed schemes, two users first sequentially broadcast their respective information to all the relays.

Improving Secrecy for Correlated Main and Wiretap Channels Using Cooperative Jamming
IEEE Access, 2019 To reduce the secrecy loss due to the correlation between main and wiretap channels, this paper introduces a cooperative jamming relay to degrade the reception at the eavesdropper.
