    • 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. ...

    • Advanced experimental setup for the reliability characterization of radio-acoustic sensors in water pipes 

      Trinchero D.; Stefanelli R.; Kadri A.; Abu-Dayya A.; Khattab T.; ... more authors ( IEEE , 2011 , Conference Paper)
      The paper presents the design and construction of a test bench for the analysis and certification of radio-acoustic sensors inside conduits filled with liquids. It is a brand new test-set that integrates the capability to ...

    • 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 ...

    • Cooperative OFDM systems for UWAC with SNR-based relay selection schemes 

      Karakaya B.; Sökün, Hamza Ümit; Uysal M.; Hasna , Mazen ( IEEE , 2012 , Conference Paper)
      In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ...

    • 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 ...
