    • Development of a new approach for high-quality quadrupling frequency optical millimeter-wave signal generation without optical filter 

      Nael A., Al-Shareefi; Syed I., S. Hassan; Mohd Fareq, Abd Malek, Dr.; Razali, Ngah, Assoc. Prof. Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Rashid Ali, Fayadh; Jaafar Adhab, ALdhaibani; Hasliza, A. Rahim (PIER, 2013)
      In this paper, we propose a new approach to generate quadrupling-frequency optical millimeter-wave (mm-wave) signal with carrier suppression by using two parallel Mach-Zehnder modulators (MZMs) in Radio-over-fiber (RoF) ...

    • The development of FPGA-based wireless channel simulator using LabVIEW 

      Nor Aswani, Mamat; Razali, Ngah, Assoc. Prof. Dr.; Chude-Okonkwo, Uche Anicetus K Chude, Dr.; Muhamad Asmi, Romli (Penerbit UTM Press, 2013)
      The development of channel model for wireless communication system is currently becoming important to fulfill the entire user's requirements and increasing demand where to provide a good communication link between the users ...

    • A new two-code keying scheme for SAC-OCDMA systems enabling bipolar encoding 

      Hamza M. R., Al-Khafaji, Dr.; Razali, Ngah, Assoc. Prof. Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Tharek, Abd. Rahman, Prof. Dr. (Taylor & Francis, 2014-03)
      In this paper, we propose a new two-code keying scheme for enabling bipolar encoding in a high-rate spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) system. The mathematical formulations are ...
