    • A cost-effective method for high-quality 60GHZ optical millimeter wave signal generation based on frequency quadrupling 

      Nael Ahmed, Al-Shareefi; Syed Idris, Syed Hassan, Prof. Dr.; Mohd Fareq, Abd. Malek, Dr.; Razali, Ngah, Assoc. Prof. Dr. ; Sura A., Abbas; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (EMW Publishing, 2013)
      In this paper, we present a cost effective method to generate a high-quality quadruple frequency optical millimeter- wave (MMW) signal using an integrated dual-parallel Mach-Zehnder modulator (IDP-MZM). Not only does the ...

      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 ...
