    • Construction of a new code for spectral amplitude coding in optical code-division multiple-access systems 

      Hasoon, Feras N.; Mohamad Khazani, Abdullah; Syed Alwee Aljunid, Syed Junid; Sahbudin, Shaari (Society of Photo-Optical Instrumentation Engineers (SPIE), 2007-07)
      An enhanced code structure for spectral amplitude coding in optical code division multiple access systems based on double weight (DW) code families is proposed. Enhanced double weight (EDW) codes possess ideal cross-correlation ...

    • Development of new OCDMA code 

      Nor Ilyana Osman (Universiti Malaysia PerlisSchool of Computer and Communication Engineering, 2007-05)
      Nowadays, communication is very important at any place, time and situation. The transmission of signal can be in wireless or cable (especially fiber optic that has more advantages than others cable for a long distance). ...

    • Improve the signal to noise ratio using AND subtraction technique in optical CDMA 

      Mohamad, Othman; Noran Azizan, Cholan; Rahmat M., Talib; Baharadin, E.; Rejab, M. F M; Syed Alwee Aljunid, Syed Junid; Mohamad Khazani, Abdullah (ACTA Press, 2008-04-02)
      AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and the simulation results have been done by comparing AND subtraction technique against Complementary subtraction technique ...

    • New code structure for spectral amplitude coding in OCDMA system 

      Hasoon, Feras N.; Syed Alwee Aljunid, Syed Junid; Mohamad Khazani, Abdullah; Sahbudin, Shaari (The Institute of Electronics, Information and Communication Engineers, 2007)
      A new code structure for spectral amplitude coding optical code division multiple access system, based on Double Weight (DW) code families is proposed. The DW code has a, fixed weight of two. Modified Double Weight (MDW) ...

    • Performance of OCDMA systems using a complementary subtraction technique 

      Hasoon, Feras N.; Mohamad Khazani, Abdullah; Syed Alwee Aljunid, Syed Junid; Sahbudin, Shaari (Optical Society of America, 2007)
      What we believe to be a new code structure to reduce the multiple access interference in a spectral amplitude coding optical code-division multiple access system based on double-weight code families is proposed. Enhanced ...

    • Random diagonal codes for spectral amplitude coding optical CDMA systems using fiber Bragg-Grating 

      Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid; R. Badlishah, Ahmad (Institute of Electrical and Electronics Engineering (IEEE), 2008-08-26)
      In this paper we study the use of a new code called Random Diagonal (RD) code for Spectral Amplitude Coding (SAC) optical Code Division Multiple Access (CDMA) networks, using Fiber Bragg-Grating (FBG), FBG consists of a ...
