Improving BER using RD Code for spectral amplitude coding optical CDMA network
(Institute of Electrical and Electronics Engineering (IEEE), 2009)
A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties ...
Compact ultra-wide band microwave filter utilizing quarter-wave length short-circuited stubs with reduced number of vias
(John Wiley & Sons Inc., 2009-09)
We present here a novel pattern with compact size of ultra-wide band microstrip filter. The filter is originally modeled from five poles quarter-wavelength short-circuited stubs. It is then, transformed into a new compact ...
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 ...
Spectral amplitude coding OCDMA using and subtraction technique
(Optical Society of America, 2008-03)
An optical decoding technique is proposed for a spectral-amplitude-coding- optical code division multiple access, namely, the AND subtraction technique. The theory is being elaborated and experimental results have been ...
Ultra-wide band microwave filter utilizing quarter-wavelength short-circuited stubs
(Wiley Periodicals, 2008-11)
Five poles quarter-wave short-circuited stubs is designed and developed to support the ultra-wide band (UWB) applications. The filter, with a total size of 41 mm × 12 mm operates within 2.7-9.83 GHz, produces a fractional ...
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 ...
Novel compact "via-less" ultra-wide band filter utilizing capacitive microstrip patch
(EMW Publishing, 2009)
This paper presents a novel compact "via-less" UWB filter derived from a quarter-wavelength short-circuited stubs model. In this compact "via-less" UWB filter, there is no connecting vias as short circuit elements. Unlike ...
Spectral amplitude coding OCDMA using and subtraction technique
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing Double-Weight (DW) code against the ...
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. ...
