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

SMS distribution and information system
(Işık Üniversitesi, 2003-07)
In this master's thesis, a web based application software package is developed using a mobile terminal (Siemens M20), for sending SMS message to individuals or groups to disseminate information to cellular-phones. Employing ...
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 ...
