    Minimizing correlation effect using zero cross correlation code in spectral amplitude coding optical code division multiple access 

    Anuar, Mat Safar, Ir. Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Amir Razif Arief, Jamil Abdullah, Dr.; Junita, Mohd Nordin; Mohamad Naufal, Mohamad Saad, Assoc. Prof. (The Optical Society of Japan, 2012-01)
    The use of minimal multiple access interference (MAI) in code design is investigated. Applying a projection and mapping techniques, a code that has a zero cross correlation (ZCC) between users in optical code division ...

    Performance analysis of wavelength multiplexed SAC OCDMA codes in beat noise mitigation in SAC OCDMA systems 

    Ahmed M., Alhassan; Nasreen, Badruddin, Dr.; Mohamad Naufal, Mohamad Saad; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (European Optical Society, 2013-07)
    In this paper we investigate the use of wavelength multiplexed spectral amplitude coding (WM SAC) codes in beat noise mitigation in coherent source SAC OCDMA systems. A WM SAC code is a low weight SAC code, where the whole ...

    Reducing BER of spectral-amplitude coding optical code-division multiple-access systems by single photodiode detection technique 

    Hamza Mohammed Ridha, Al-Khafaji; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Amphawan, Angela, Dr.; Hilal Adnan, Fadhil, Dr.; Anuar, Mat Safar, Ir. Dr. (European Optical Society, 2013-03)
    In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity ...

    Improved BER based on intensity noise alleviation using developed detection technique for incoherent SAC-OCDMA systems 

    Hamza Mohammed Ridha, Al-Khafaji; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr. (Taylor and Francis Group, LLC., 2012-06)
    The major drawback of incoherent spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems is their inherent intensity noise originating due to the incoherency of the broadband light sources. In ...

    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 ...
