Performance analysis of optical zero cross correlation in OCDMA system
(Asian Network for Scientific Information, 2007)
We propose a new code structure for Spectral-Amplitude Coding Optical Code Division Multiple Access (OCDMA) systems with zero cross-correlation and theoretically demonstrate the performance of this code by using a direct ...
Equation-based construction technique for the OSCDMA zero cross correlation code for the basic matrix
(Institute of Electrical and Electronics Engineering (IEEE), 2007-05)
In this paper the Double Weight code (DW) family which is used as a proposed code in optical spectral code division multiple access system (OSCDMA) has been studied using the Modified Double Weight code (MDW) which has ...
New approach of Double Weight Code Family Detection using reduced set of Fiber Bragg Gratings
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
To increase the number of users in the double weight (DW) code family, a mapping technique is applied. This mapping technique increases the number of users but at a cost of unfixed cross-correlation property. The complementary ...
Design of encoder and decoder module for optical code division multiple access (OCDMA) systems for zero cross correlation (ZCC) code based on arrayed waveguide gratings (AWGs)
(Institute of Electrical and Electronics Engineering (IEEE), 2008-12-01)
We apply the Arrayed Waveguide Grating (AWGs) method for Encoder and Decoder design for complete transmitter and receiver system. The Encoder and Decoder module will be using the AWG to encode and to decode optical source ...
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. ...
Improving bit error rate of OCDMA systems using and subtraction technique
