Effects of the Random Diagonal code link parameters on the performance of an OCDMA scheme for high-speed access networks
(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 ...
Performance of random diagonal code for OCDMA systems using new spectral direct detection technique
(Elsevier Inc, 2009-01-31)
This paper studies the performance of random diagonal (RD) code for spectral-amplitude coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection technique. RD code is constructed using code segment ...
New design of spectral amplitude coding in OCDMA with zero cross-correlation
(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. ...
Spectral efficiency of unipolar SAC-OCDMA system considering noise effects
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-25)
In this paper, we evaluate the spectral efficiency of unipolar spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) system operating with incoherent sources in the present of intensity, shot, and ...
Multi-rate transmissions on spectral amplitude coding optical code division multiple access system using random diagonal codes
(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 ...
Phase-induced intensity noise reduction with improved group velocity dispersion tolerance in SAC-OCDMA systems
