Development of new OCDMA code
(Universiti Malaysia Perlis, 2007-05)
Nowadays, communication is very important at any place, time and situation. The transmission of signal can be in wireless or cable (especially fiber optic that has more advantages than others cable for a long distance). ...
Spectral amplitude coding OCDMA: Performance analysis on detection schemes using vectors combinatorial code families
(Fachverlag Schiele and Schoen GmbH, 2009)
In Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) system, Multip-user Interference (MUI) problem which increases with the number of users severely limits the performance of the system. However, ...
Minimizing correlation effect using zero cross correlation code in spectral amplitude coding optical code division multiple access
(The Optical Society of Japan, 2012-01)
The use of minimal multiple access interference (MAI) in code design is investigated. Applying a projection and mapping techniques, a code that has a zero cross correlation (ZCC) between users in optical code division ...
Development of new OCDMA detection scheme
(Universiti Malaysia Perlis, 2007-03)
A new direct detection technique is proposed for optical code multiple accesses using
Double Weight code. In optical system the detection process affect design transmitter and receiver. The Multiple Access Interference ...
Triple-play services using random diagonal code for spectral amplitude coding OCDMA systems
(Fachverlag Schiele and Schoen GmbH, 2009)
In this paper, a new code called Random Diagonal (RD) code for spectral amplitude coding optical code division multiple access (OCDMA) networks is presented. This code is compared with other codes like MQC, MFH and Hadamard ...
Performance analysis of wavelength multiplexed SAC OCDMA codes in beat noise mitigation in SAC OCDMA systems
(European Optical Society, 2013-07)
In this paper we investigate the use of wavelength multiplexed spectral amplitude coding (WM SAC) codes in beat noise mitigation in coherent source SAC OCDMA systems. A WM SAC code is a low weight SAC code, where the whole ...
Performance of OCDMA systems with new spectral direct detection (SDD) technique using enhanced double weight (EDW) code
(Elsevier B.V., 2008-09-15)
This paper investigates the performance of enhanced double weight (EDW) code for spectral-amplitude-coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection (SDD) technique. EDW is the enhanced ...
Performance of OCDMA systems using a complementary subtraction technique
(Optical Society of America, 2007)
What we believe to be a new code structure to reduce the multiple access interference in a spectral amplitude coding optical code-division multiple access system based on double-weight code families is proposed. Enhanced ...
Reducing BER of spectral-amplitude coding optical code-division multiple-access systems by single photodiode detection technique
(European Optical Society, 2013-03)
In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity ...
