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 ...
Optical domain service differentiation using spectral-amplitude-coding
(Elsevier Inc., 2009)
We have implemented a new service differentiation technique in the optical domain using a spectral-amplitude-coding (SAC) variant of optical code division multiple access (OCDMA). The newly developed code, named KS ...
