An experimental performance evaluation of the hybrid FSO/RF
( SPIE , 2017 , Conference Paper)This paper is a first attempt to study the effects of atmospheric turbulences on hybrid free space optics/ radio frequency (FSO/RF) transmission system in Doha, Qatar. The state of Qatar is characterized by a Mediterranean ... -
Area spectral efficiency of cooperative network with DF and AF relaying
( IEEE , 2012 , Conference Paper)Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ... -
Area spectral efficiency of underlay cognitive radio transmission over rayleigh fading channels
( IEEE , 2013 , Conference Paper)Cognitive radio is a promising technology to improve the spectrum utilization by allowing the unlicensed (secondary) user share a frequency bandwidth with the licensed (primary) owner under the condition that no harmful ... -
Self-Energized UAV-Assisted scheme for cooperative wireless relay networks
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)Unmanned aerial vehicles (UAVs) have recently been envisaged as an enabling technology of 5G. UAVs act as an intermediate relay node to facilitate uninterrupted, high quality communication between information sources and ... -
Theoretical accuracy analysis of indoor visible light communication positioning system based on time-of-arrival
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, an improved channel model and estimation for positioning in indoor environments using the visible light is presented. For positioning, the specific propagation and indoor channel model for visible light is ...
