    • A divided spectrum balanced detection technique for intensity noisereduction in SAC OCDMA systems 

      Ahmed M., Alhassan; Nasreen, Badruddin, Dr.; Mohamad Naufal, Mohamad Saad; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (Elsevier GmbH, 2013-12)
      In this paper we propose a simple divided spectrum balanced detection (DSBD) for spectral amplitudecoding (SAC) optical code division multiple access (OCDMA) systems. SAC OCDMA systems are limited byphase induced intensity ...

    • New design of spectral amplitude coding in OCDMA with zero cross-correlation 

      Anuar, Mat Safar; Syed Alwee Aljunid, Syed Junid; N. M., Saad; S. M., Hamzah (Elsevier B.V. (Imprint: NORTH-HOLLAND), 2009-07)
      A zero cross-correlation (ZCC) code is proposed to reduce the impact of system impairment and multiple access interference (MAI) in spectral amplitude coding optical code division multiple access (SAC-OCDMA) system. ...

    • Performance evaluation of SAC-OCDMA using direct detection techniques 

      Norazimah, M. Z.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      In optical code division multiple access (OCDMA), noise give a big effect in degrading the performance of the system. Theoretically, direct detection technique can successfully suppressed or eliminate the dominant noise ...

    • Variable cross-correlation code construction for spectral amplitude coding optical CDMA networks 

      Hilal Adnan, Fadhil, Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hassan Y., Ahmed; Hamza Mohammed Ridha, Al-Khafaji (Elsevier Ltd., 2012-06)
      We present, for the first time, several aspects of incoherent optical code-division multiple access (OCDMA) codes, focusing on the flexible variable cross-correlation code allocation and its potential for future optical ...
