Channels estimation in OFDM system on block-type and comb-type pilot arrangement
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
In orthogonal frequency division multiplexing (OFDM) systems over time-varying and frequency-selective fading channel, channel estimation and tracking is generally carried out by transmitting known pilot symbols in given ...
New code with non-zero cross correlation for spectral amplitude coding optical code-division multiple-access systems
(Institute of Electrical and Electronics Engineers (IEEE), 2012-05-21)
This paper presented the novel of a new class of code with Non-Zero Cross-Correlation for Spectral-Amplitude Coding in Optical Code Division Multiple Access (OCDMA) systems. A new code namely Modified Non-Zero Cross ...
Effective design for fiber-to-the-home access network using flexible cross correlation (FCC) code
(Trans Tech Publications, 2014-01)
This paper presented a new class of codes for Fiber-To-The-Home (FTTH) network design based on Spectral Amplitude Coding (SAC) - Optical Code Division Multiple Access (OCDMA) coding approaches. The FTTH SAC-OCDMA network ...
New class of code with any desired cross correlation for OCDMA systems
(Institute of Electrical and Electronics Engineers (IEEE), 2012-04-07)
This paper presented the novel of optical code for Optical Code Division Multiple Access (OCDMA) system using Spectral Amplitude Coding. A new class of code, called Modified Non-Zero Cross Correlation Code (MNZCC). MNZCC ...
Detection of wrist movement using EEG signal for brain machine interface
(Institute of Electrical and Electronics Engineers (IEEE), 2013-06)
Brain machine interfaces (BMIs) allow patients suffering from neuromuscular disorders to control the movement of robotic limb or wheelchair under their own guidance. So far only invasive technologies e.g. Electrocorticography ...
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)
In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ...
Development and performance evaluation of hierarchical quadrature amplitude modulation (HQAM) for image transmission over wireless channels
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-20)
Asymmetric modulation techniques like Quadrature Amplitude Modulation system is one of the key techniques in building a broadband mobile communication network because of increasing shortage of wireless communication channels. ...
Waveform design for improved range and Doppler resolution in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02)
The choice of a suitable transmit waveform is an important problem in radar design. This is so because the waveform controls resolution and clutter performance and also bears heavily on the system cost. Theoretical studies ...
Effect of two different superstrate layers on Bismuth Titanate (BiT) array antennas
(Macmillan Publishers Limited, 2014-01)
The microwave industry has shown increasing interest in electronic ceramic material (ECM) due to its advantages, such as light weight, low cost, low loss, and high dielectric strength. In this paper, simple antennas covered ...
New design of Flexible Cross Correlation (FCC) code for SAC-OCDMA system
(Elsevier B.V., 2013)
In this paper, we present, several aspects of unipolar optical code-division multiple access (OCDMA) codes, focusing on the flexible inphase cross-correlation code algorithm and its potential for future optical networks. ...
