Physical Layer Security for TAS/MRC Systems With and Without Co-Channel Interference Over Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, the secrecy performance of transmit antenna selection/maximal ratio combining systems in the absence and presence of co-channel interference (CCI) over ?-? fading channels is considered. In particular, ...
Outage Performance of UAV-Assisted Relaying Systems with RF Energy Harvesting
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this letter, we propose an UAV-based relaying system with energy harvesting functionality. In particular, we assume that this system is operated in urban communication environments, where the channel between the UAV and ...
On the performance of LAP-based multiple-hop RF/FSO systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, we propose a low-altitude aerial platform (LAP) based relaying system, where two LAPs serve as relays. More specifically, the air-to-ground links are assumed to be radio frequency (RF) channels experiencing ...
On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...
Average outage duration of multihop communication systems with regenerative relays
(
IEEE
, 2005 , Article)
Closed-form expressions for the average outage duration (AOD) of multihop regenerative communication systems over generalized fading channels are presented. Both noise-limited and interference-limited systems are studied. ...
Asymptotic BER analysis of FSO with multiple receive apertures over M-distributed turbulence channels with pointing errors
(
Optical Society of American (OSA)
, 2014 , Article)
In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over M-distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes ...
Performance Analysis of Amplify-and-Forward Hybrid Satellite-Terrestrial Networks with Cochannel Interference
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...
A novel energy harvesting scheme for mixed fso-rf relaying systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this correspondence paper, we consider the performance of a mixed free-space optical and radio frequency (FSO-RF) relaying system with energy harvesting in the existence of both atmospheric turbulence and pointing errors. ...
Secrecy Performance Analysis of RIS-Aided Wireless Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-aided wireless communication system in the presence of an eavesdropping user. Specifically, we assume that the RIS is placed ...
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 ...
