Investigation the performance of unipolar SAC-OCDMA codes
(AENSI Publications, 2012-01)
In this paper, we investigate the performance of unipolar Spectral Amplitude Coding Optical Code Division multiple Access (SAC-OCDMA) codes. A performance comparison made between various unipolar SAC-OCDMA codes such as ...
New approach for evaluation of the performance of spectral amplitude coding-optical code division multiple access system on high-speed data rate
(The Institution of Engineering and Technology, 2012-08-14)
In this study, the authors proposed a new approach to evaluate the system performance of spectral amplitude codingoptical
code division multiple access (SAC-OCDMA) systems. The system performance is evaluated based on a ...
Hybrid OCDMA over WDM system using modified double weight (MDW) code for optical access network
(Trans Tech Publications, 2012)
In this paper a hybrid optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) network is proposed to support large number of subscribers. The system combines two different techniques, ...
Enhancement of performance of a hybrid SAC–OCDMA system using dynamic cyclic shift code
(Institute of Physical Optics, 2012)
A hybrid subcarrier multiplexing (SCM) technique incorporating spectral amplitude coding and optical code division multiple access (SAC-OCDMA) technologies is investigated using both numerical and simulation methods. The ...
Variable cross-correlation code construction for spectral amplitude coding optical CDMA networks
(Elsevier Ltd., 2012-06)
We present, for the first time, several aspects of incoherent optical code-division multiple access (OCDMA) codes, focusing on the flexible variable cross-correlation code allocation and its potential for future optical ...
Design and simulation a new code with zero cross-correlation for SAC-OCDMA networks
(INSInet Publications, 2012-03)
Design and simulation of new code family for the Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) networks is present. The new code family called Multi Diagonal (MD) code. The MD code family ...
Improved BER based on intensity noise alleviation using developed detection technique for incoherent SAC-OCDMA systems
(Taylor and Francis Group, LLC., 2012-06)
The major drawback of incoherent spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems is their inherent intensity noise originating due to the incoherency of the broadband light sources. In ...
Modelling and simulation of a 1.6 Tb/s optical system based on multi-diagonal code and optical code-division multiple-access
(Institute of Physical Optics, 2012)
n this paper we have modelled and simulated a 1.6 Tb/s (100×16 Gb/s) optical system based on spectral amplitude coding for the optical code-division multiple- access (SAC-OCDMA) scheme. In order to reduce the effect of ...
