Multiuser Relay Networks Over Unreliable Backhaul Links Under Spectrum Sharing Environment

open access: yesIEEE Communications Letters, 2017
The effects of unreliable backhaul links on cognitive relay networks with best user selection over Nakagami- $m$ fading are investigated. In particular, closed-form expressions for the critical performance metrics are derived along with the asymptotic performance to obtain insights into the impact of the backhaul reliability and multiuser ...

Secure Cooperative Systems With Jamming and Unreliable Backhaul Over Nakagami-m Fading Channels

open access: yesLecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, 2019
In this paper, the secrecy performance of cooperative networks with jamming signals of eavesdroppers are studied under the impacts of unreliable backhaul networks. By proposing a two-phase transmitter/relay selection scheme, the desired signal-to-noise ratio (SNR) of relays is maximized by selected the best transmitter, meanwhile, the jamming signal-to-
