Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Article)
In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ...
A Novel RIS-Assisted Modulation Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this work, in order to achieve higher spectrum efficiency, we propose a reconfigurable intelligent surface (RIS)-assisted multi-user communication uplink system. Different from previous work in which the RIS only optimizes ...
Reactive relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
Best relay selection is a bandwidth efficient technique for multiple relay environments without compromising the system performance. The problem of relay selection is more challenging in underlay cognitive networks due to ...
A performance study of dual-hop transmissions with fixed gain relays
(
IEEE
, 2004 , Article)
This letter presents a study on the end-to-end performance of dual-hop wireless communication systems equipped with nonregenerative fixed gain relays and operating over flat Rayleigh-fading channels. More specifically, it ...
Performance of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider a free-space optical (FSO) communication scheme with the help of a variable gain relay where the links from the source to the relay are radio-frequency (RF) links while the links between the relay ...
