The effect of total noise on two-dimension OCDMA codes

open access: yesEPJ Web of Conferences, 2017
In this research, we evaluate the performance of total noise effect on two dimension (2-D) optical code-division multiple access (OCDMA) performance systems using 2-D Modified Double Weight MDW under various link parameters.

In situ method for power re-equalization of wavelength pulses inside of OCDMA codes [PDF]

open access: yes, 2011
A simple in-situ method to equalize power among individual wavelengths pulses representing two-dimensional wavelength-hopping time-spreading OCDMA code originally generated by a fibre Bragg grating-based OCDMA encoder is presented.

Performance survey of classic and Optic network‐on‐chip

open access: yesIET Circuits, Devices &Systems, Volume 15, Issue 4, Page 393-402, July 2021., 2021
Abstract A system on chip is composed of a large number of intellectual property (IP) blocks on the same silicon. However, as the number of IP blocks on a single chip and their performance continue to increase, a shift from those classic interconnections to optical ones becomes mandatory. This article presents a survey and comparison between an optical

Capacity Improvement of 3D-OCDMA-PON Hybrid System Next Generation Using Weight Zero Cross Correlation Code

open access: yesApplied Sciences, 2023
This paper proposes a novel code for optical code division multiple access (OCDMA) systems, called the three-dimensional (3D) spectral/temporal/spatial single weight zero cross-correlation (3D-SWZCC) code.

Chip-Asynchronous Binary Optical CDMA: An Optimum Signaling Scheme for Random Delays

open access: yesIEEE Photonics Journal, 2013
Most optical code division multiple access (OCDMA) research literature has focused on chip-synchronous OCDMA. However, practical OCDMA networks are inherently chip-asynchronous since users transmit their signals from different locations without any ...
