    • 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 ...

    • Experimental setup to validate the effects of major environmental parameters on the performance of FSO communication link in Qatar 

      Khandakar A.; Touati A.; Touati F.; Abdaoui A.; Bouallegue A. ( MDPI AG , 2018 , Article)
      Weather conditions and chemical composition of the atmosphere are the most uncontrollable challenges for free-space optical (FSO) communications. Environmental parameters contribute directly in the characterization of ...

    • HARQ Performance over FSO Channels with Atmospheric Fading and Pointing Errors 

      Touati A.; Hasna M.O.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)
      Free space optical communications (FSO) have witnessed a growing interest in the last few decades due to its various advantages. However, this technology suffers from its sensitivity to the atmospheric conditions such as ...

    • Indoor test of the fog's effect on FSO link 

      Touati A.; Abdaoui A.; Touati F.; Khandakar A.; Bouallegue A. ( SPIE , 2017 , Conference Paper)
      In order to distinguish the most rigorous model, we made a comparison between measurements data and the mostly used empirical models. These models use the visibility as a basic parameter to predict the fog attenuation. In ...

    • 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 ...
