Significance map pruning and other enhancements to SPIHT image coding algorithm
(Elsevier Science, 2003-10)
This paper proposes several enhancements to the Set Partitioning in Hierarchical Trees (SPIHT) image coding algorithm without changing the original algorithm's general skeleton. First and foremost, a method for significance ...
A note on the exact travelling wave solution to the KdV-Burgers equation
(Elsevier Science, 2003-10)
In the present note, by use of the hyperbolic tangent method, a progressive wave solution to the Korteweg-de Vries-Burgers (KdVB) equation is presented. The solution we introduced here is less restrictive and comprises ...
EM-Based sequence estimation for wireless systems with orthogonal transmit diversity
(IEEE, 2003)
In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
Microwave amplifier design for mobile communication via immittance data modelling
(IEEE, 2003)
In this paper, a practical broadband microwave amplifier design algorithm based on immittance data modelling is presented. In the course of design, first, the optimum input and output terminations for the active device are ...
A parametric approach to describe distributed two-ports with lumped discontinuities for the design of broadband MMIC's
(IEEE, 2003)
This paper addreses the use of mixed lumped and distributed elements in the matching equalizers of broadband microwave communication subsytems in MMIC realizations. Construction of two-variable scattering functions for ...
Design and simulation of miniaturized communication systems employing symmetrical lossless two-ports constructed with two kinds of elements
(IEEE, 2003)
In this paper, a semi-analytic method is presented to describe symmetrical lossless networks with two-kinds of elements, namely, distributed and lumped elements in cascade connection. in terms of the independently chosen ...
New criteria for the existence of stable equilibrium points in nonsymmetric cellular neural networks
(2003)
This paper presents new criteria for the existence of stable equilibrium points in the total saturation region for cellular neural networks (CNNs). It is shown that the results obtained can be used to derive some complete ...
Gezgin iletişim için uzay-zaman kodlamalı çok-taşıyıcılı tümleşik sistem tasarımı
(Tübitak, 2003-04)
Günümüzde önemi hızla artan gezgin ve telsiz (mobile/wireless) iletişim sistemleri (uydu iletişimi, gezgin radyo, “indoor” iletişim) iletişim kanalının neden olduğu toplamsal Gauss gürültüsüne ek olarak sönümlemeden (fading) ...
Phased subarray imaging for low-cost, wideband coherent array imaging
(IEEE, 2003)
The front-end hardware complexity of conventional full phased array (FPA) imaging is proportional to the number of array elements. Phased subarray (PSA) imaging has been proposed as a method of reducing the hardware ...
Computational model of the ventricular action potential in adult spontaneously hypertensive rats
(2003-09-01)
Introduction: Cardiac hypertrophy has substantial clinical significance because many hypertrophic cells have markedly prolonged repolarization behavior, which may lead to increased risk for cardiac arrhythmias. Spontaneously ...
