    • Comparison of wavelength propagation for free space optical communications 

      Naimullah, B. S S; Mohamad, Othman; Rahman, A. K.; Suzana, I. Sulaiman; Ishak, S.; Salasiah, Hitam; Syed Alwee Aljunid, Syed Junid (Institute of Electrical and Electronics Engineering (IEEE), 2008)
      This paper presents the effect of atmospheric attenuation during severe hazy days for Free Space Optical Communications. The usage of Free Space Optical Communications is still rare in Malaysia due to environment factor. ...

    • Performance Evaluation of a Novel Optimization Sequential Algorithm (SeQ) Code for FTTH Network 

      Fazlina, C. A. S.; Mohd Rashidi, Che Beson; Rahman, A. K.; Syed Alwee Aljunid, Syed Junid (EDP Sciences, 2017)
      The SeQ codes has advantages, such as variable cross-correlation property at any given number of users and weights, as well as effectively suppressed the impacts of phase induced intensity noise (PIIN) and multiple access ...

    • Performance evaluation of downlink design based on free space optical system 

      Anis Afina, Azman; Mohd Rashidi, Che Beson; Rahman, A. K.; Syed Alwee Aljunid, Syed Junid; Yaakob, S. (EDP Sciences, 2017)
      In this paper, the performance of downlink design utilizing the free space optic (FSO) is presented. The permissible BER of 10-58 is achieved when the system utilized 40 cm aperture diameter. The highest system sensitivity ...
