    • Compressing Turbulence Effect in FSO using New Modulation Technique 

      Norizan, Mohamed Nawawi; Anuar, Mat Safar; Abdul Rahman, Kram; Mohd Rashidi, Che Beson; Junita, Mohd Nordin (EDP Sciences, 2017)
      Diffusers transmitter modulation to reduce the effect of atmospheric turbulence in free space optical communication system is described in this paper. This technique uses dual transmitters and dual receivers which are using ...
    • Enhance the performance of free space optical (FSO) communication due to atmospheric turbulence via the dual diffuser modulation (DDM) 

      Abdul Rahman, Kram; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Anuar, Mat Safar, Ir. Dr.; Hilal Adnan, Fadhil, Dr. (Trans Tech Publications, 2013-12)
      This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using dual diffuser modulation (DDM) technique. Phase screen diffuser located on transmitter create 'new' beam wave to ...
