The Arbitrarily Varying Relay Channel [PDF]

open access: yesEntropy, 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]

open access: yesEntropy
Relay 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 ...

Harmful Cooperation in Relay-Assisted MIMO Under Imperfect CSI [PDF]

open access: yesSensors
This paper investigates the performance of cooperative multiple-input multiple-output (MIMO) systems under practical operating impairments, with particular emphasis on imperfect channel state information (CSI) and relay decoding errors.

A simple Encoding Scheme to Achieve the Capacity of Half-Duplex Relay Channel

open access: yesAdvances 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.

Beamforming for Dual-Hop MIMO AF Relay Networks With Channel Estimation Error and Feedback Delay

open access: yesIEEE Access, 2017
This paper concerns the beamforming (BF) design for a dual-hop multiple-input multiple-output (MIMO) amplify-and-forward (AF) relay network. Both a general antenna configuration and imperfect channel state information are taking into consideration, where

Information Bottleneck for a Rayleigh Fading MIMO Channel with an Oblivious Relay

open access: yesInformation, 2021
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to operating without knowledge of the codebooks, i.e., it performs oblivious ...
