Design considerations of high performance optical code division multiple access: A new spectral amplitude code based on laser and light emitting diode light source
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid, Prof. Madya; R. Badlishah, Ahmad, Prof. Madya Dr. (The Institution of Engineering and Technology, 2010-02-01)A new code of optical code division multiple access (OCDMA) based on spectral amplitude coding (SAC) is described and analysed. The coding technique is called random diagonal (RD) code. One of the important properties of ... -
Development of a new code family based on SAC-OCDMA system with large cardinality for OCDMA network
Thanaa Hussein, Abd; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil; R. A., Ahmad; Mohamad Naufal, Mohamad Saad, Dr. (Elsevier Inc., 2011-07)We have proposed a new Multi-Diagonal (MD) code for Spectral Amplitude - Coding Optical Code Division Multiple Access (SAC-OCDMA). Although this new MD code has many properties, one of the important properties of this code ... -
Effects of the Random Diagonal code link parameters on the performance of an OCDMA scheme for high-speed access networks
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid; R.Badlishah, Ahmad (Elsevier Inc., 2009-06)In this paper, we study the performance of optical code-division multiple access (OCDMA) systems using Random Diagonal (RD) code under various link parameters. This code which can be constructed using address segment and ... -
Multi-rate transmissions on spectral amplitude coding optical code division multiple access system using random diagonal codes
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid; R.Badlishah, Ahmad (Institute of Physics, Wroclaw University of Technology, 2009)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 (OCDMA) networks, using fiber Bragg-grating (FBG). FBG consists of a ... -
New code structure for spectral amplitude coding OCDMA system
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid; R. Badlishah, Ahmad (The institute of Electronics, Information and Communication Engineers (IEICE), 2008-10)A new code structure for spectral amplitude coding in optical code division multiple access (OCDMA) systems called Smart Direct Detection (SDD) code is proposed. SDD code is constructed using code segment and data segment. ... -
Performance of optical OFDM systems using new PAPR reduction approach
Hilal Adnan, Fadhil; Hasoon, Feras N.; Syed Alwee Aljunid, Syed Junid; Ahmad, H. Y.; Hamza Mohammed Ridha, Al-Khafaji (EBSCO Publishing., 2012-03)The major drawback of optical orthogonal frequency division multiple access (OFDM) system is their inherent intensity noise and peak average power ratio (PAPR). We introduce a new direct detection receiver based on PAPR ... -
