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 ...
Memory efficient set partitioning in hierarchical tree (MESH) for wavelet image compression
(The Institute of Electronics, Information and Communication Engineers., 2012-09)
This paper presents a memory efficient version of set partitioning in hierarchical tree (SPIHT). The proposed coder called Memory Efficient SPIHT (MESH) uses a single re-usable list instead of three continuously growing ...
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 ...
Signal propagation analysis for low data rate wireless sensor network applications in sport grounds and on roads
(EMW Publishing, 2012)
This paper presents results of a study to characterise wire- less point-to-point channel for wireless sensor networks applications in sport hard court arenas, grass fields and on roads. Antenna height and orientation effects ...
Comparison between two types of computer for Industrial Ethernet performance
(Trans Tech Publications, 2012)
Ethernet is now the dominant networking in the home and office environment. Advanced of the network technology and convergence of communications, control and computer enabled the Networked Control System (NCS). Industrial ...
Performance of optical OFDM systems using new PAPR reduction approach
(EBSCO Publishing., 2012-03)
The major drawback of optical orthogonal frequency division multiple access (OFDM) system is their inherent intensity noise and peak average power ratio (PAPR). We introduce a new direct detection receiver based on PAPR ...
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 ...
Gait disorder rehabilitation using vision and non-vision based sensors: a systematic review
(Association of Basic Medical Sciences of Federation of Bosnia and Herzegovina, 2012)
Even though the amount of rehabilitation guidelines has never been greater, uncertainty continues to arise regarding the efficiency and effectiveness of the rehabilitation of gait disorders. This question has been hindered ...
