Performance of random diagonal code for OCDMA systems using new spectral direct detection technique
(Elsevier Inc., 2009-06)
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 ...
Identification of LPI radar signals by higher order spectra and neural network techniques
(Inderscience Publishers, 2009)
LPI radars use continuous wave, wide bandwidth low power signals of the order of a few watts making its detection difficult. The important advantage of LPI radar is to go undetected, while maintaining a strong battlefield ...
Design and analytical modeling of folded waveguide traveling wave tube
(Elsevier B. V., 2009-12-21)
We are developing a simple analytical model for the design of the folded waveguide traveling wave tube (FWTWT). Numerical software does exist for the design of FWTWT but requires large computer run time, is costly and does ...
The analytical design of a folded waveguide traveling wave tube and small signal gain analysis using madey's theorem
(EMW Publishing, 2009)
We are developing an analytical model for the design of the folded waveguide traveling wave tube (FWTWT). This analytical model provides the physical view for rapid design optimization of the FWTWT. The design and analysis ...

Reduced complexity optimum detector for block data transmission systems
(The Institute of Electronics, Information and Communication Engineers, 2009-12-10)
Block Data Transmission Systems (BDTS) are used in high-speed wireless communication systems with time dispersive channel characteristics. In such systems, blocks of data are separated by zeros to mitigate the effect of ...
A CWDM/DWDM arrayed waveguide grating based on photodefinable polymer
(Institutul National de Cercetare-Dezvoltare pentru Optoelectronica, 2009-01)
New design of conventional AWG structures for CWDM/DWDM application based on photodefinable BenzoCyclobutene (BCB 4024-40) polymer is presented. The devices are designed on BK7 glass substrate and thin layer of SiO2 as ...

Multi-rate transmissions on spectral amplitude coding optical code division multiple access system using random diagonal codes
(Institute of Physics, Wroclaw University of Technology, 2009)
In this paper, we study the use of a new code called random diagonal (RD) code for spectral amplitude coding (SAC) optical code division multiple access (OCDMA) networks, using fiber Bragg-grating (FBG). FBG consists of a ...
Multiband fractal planar inverted F antenna (F-PIFA) for mobile phone application
(EMW Publishing, 2009)
The design of a novel Fractal planar inverted F antenna (F-PIFA) based on the self affinity property is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and three different ...
