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 ...
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 ...
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 ...
The effects of MAC protocols on ad hoc on-demand distance vector (AODV) routing protocol
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
Ad hoc networks play an important role in mobile radio networks due to its flexibility and low operation cost. Several of key research issues of ad hoc network are on the
routing and MAC algorithms. But, only a few of ...
8 channel serial controller for Remotely Operated Vehicle (ROV) applications
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
Underwater robot is a combination of
microcontroller system, mechanical system and communication system between robot and PC. In this research, controller hardware is designed for Remotely Operated Vehicle (ROV)
usage. ...
Extraction of visual information from simplified raster images
(Universiti Malaysia Perlis (UniMAP), 2007-08)
Simplification of raster images, with
irrelevant details of a visual query,
eliminates most useless elements,
while retaining perceptually dominant
elements and shape, speeds up
queries. The simplification is widely ...
