Effective design of optical code-division multiple access network using random diagonal codes
Hilal Adnan, Fadhil, Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; R. Badlishah, Ahmad, Assoc. Prof. Dr. (Institute of Electrical and Electronics Engineers (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 ... -
New code structures based on coherent and incoherent sources for spectral amplitude coding-OCDMA systems
Hilal Adnan, Fadhil, Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; R. Badlishah, Ahmad, Assoc. Prof. Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2009-04-03)A new code of optical code division multiple access (OCDMA) based on Spectral Amplitude Coding (SAC) is described and analyzed. The coding technique is called Random Diagonal "RD" code. One of the important properties of ... -
Performance improvement of spectral amplitude coding-optical code division multiple access systems using NAND detection with enhanced double weight code
Nasim, Ahmed; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; R. Badlishah, Ahmad, Assoc. Prof. Dr. (The Optical Society of Japan, 2012-01)The bit-error rate (BER) performance of the spectral amplitude coding-optical code division multiple access (SACOCDMA) system has been investigated by using NAND subtraction detection technique with enhanced double weight ...
