High Gain and High Directive of Antenna Arrays Utilizing Dielectric Layer on Bismuth Titanate Ceramics
(Hindawi Publishing Corporation, 2012-06-25)
A high gain and high directive microstrip patch array antenna formed from dielectric layer stacked on bismuth titanate (BiT) ceramics have been investigated, fabricated, and measured. The antennas are designed and constructed ...
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 ...
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 ...
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 ...
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 ...
Elbow movement detection using brain computer interface
(Institute of Electrical and Electronics Engineers (IEEE), 2012-04)
This paper investigates effectiveness of using a non-invasive Electroencephalographic (EEG) activity for Brain Computer Interface, to analyze the brain activity and translate human elbow movement into the movement of an ...
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 ...
