    • A novel energy harvesting scheme for mixed fso-rf relaying systems 

      Chen J.; Yang L.; Wang W.; Yang H.-C.; Liu Y.; ... more authors ( 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. ...

    • An experimental performance evaluation of the hybrid FSO/RF 

      Touati A.; Touati F.; Abdaoui A.; Khandakar A.; Hussain S.J.; ... more authors ( 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 ...

    • Atmospheric turbulence effect on hybrid FSO/RF systems 

      Touati A.; Hussain S.J.; Touati F.; Bouallegue A. ( IEEE Computer Society , 2017 , Conference Paper)
      This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ...

    • Evaluation of FSO link throughput in Qatar 

      Hussain S.J.; Touati A.; Elamri M.; Touati F.; Uysal M. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      Despite the vibrant advantages of Free Space Optics (FSO) technology and the variety of its applications, its widespread adoption has been hampered by rather disappointing link reliability for long-range links due to ...

    • Performance of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels 

      Yang L.; Hasna , Mazen; Gao X. ( 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 ...

    • Prospects and challenges of free space optical communications 

      Touati A.; Touati F.; Abdaoui A.; Khandakar A.; Bouallegue A. ( Springer Verlag , 2018 , Conference Paper)
      Free space optical (FSO) transmission is a technology which uses a narrow laser beam to transmit the signal from the source to the destination through the free space. Although it has various advantages, a laser beam ...

    • Unified Performance Analysis for Multiuser Mixed η - μ and M - Distribution Dual-Hop RF/FSO Systems 

      Yang, Liang; Hasna, Mazen O.; Ansari, Imran Shafique ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      A mixed free-space optical (FSO) communication scheme is considered with the help of a fixed gain relay. We assume that the links from the source to the relay are radio frequency links with multiuser diversity operating ...
