Deep Learning Assisted Antenna Selection in Untrusted Relay Networks

open access: yes, 2019
This letter mainly studies the transmit antenna selection(TAS) based on deep learning (DL) scheme in untrusted relay networks. In previous work, we discover that machine learning (ML)-based antenna selection schemes have small performance degradation caused by complicated coupling relationship between achievable secrecy rate and the channel gains.

Joint Power Allocation at the Base Station and the Relay for Untrusted Relay Cooperation OFDMA Network

open access: yesInternational Journal of Antennas and Propagation, 2015
The secure communication that multiple OFDMA-based cell-edge mobile stations (MS) can only transmit confidential messages to base station (BS) through an untrusted intermediate relay (UR) is discussed.

Joint power control for untrusted relay cooperation-based confidential communication

open access: yesTongxin xuebao, 2014
The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure ...

Protecting Against Untrusted Relays: An Information Self-encrypted Approach

open access: yes, 2017
The reliability and transmission distance are generally limited for the wireless communications due to the severe channel fading. As an effective way to resist the channel fading, cooperative relaying is usually adopted in wireless networks where neighbouring nodes act as relays to help the transmission between the source and the destination.
