    • Development of new code for optical code division multiple access systems 

      Hilal Adnan, Fadhil (Universiti Malaysia PerlisSchool of Computer & Communication Engineering, 2010)
      The main arguments for using Optical Code Division Multiple Access (OCDMA) are the flexibility of an asynchronous access method, increased security and graceful degradation. Over the last decade, many codes were proposed ...

      In this paper the Double Weight code (DW) family which is used as a proposed code in optical spectral code division multiple access system (OSCDMA) has been studied using the Modified Double Weight code (MDW) which has ...

    • 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. ...

    • A novel 2-D wavelength-time Optical Code Division Multiple Access (OCDMA) code for high-performance system 

      Amir Razif Arief, Jamil Abdullah (Universiti Malaysia Perlis (UniMAP)School of Computer and Communication Engineering, 2013)
      The explosive growth of bandwidth demand, together with advance in latest communication services and emerging applications has inspired huge interest in application of code division multiple access (CDMA) technique in ...

    • PIN versus Avalanche photodiode gain optimization in zero cross correlation optical code division multiple access system
