Option Pricing by the Legendre Wavelets Method
Computational Economics, 2021This paper presents the numerical solution of the Black–Scholes partial differential equation (PDE) for the evaluation of European call and put options. The proposed method is based on the finite difference and Legendre wavelets aproximation scheme. We derive a matrix structure for the Legendre wavelets integral operator which has been widely used so ...

Properties of extended Legendre wavelets
2008 International Conference on Wavelet Analysis and Pattern Recognition, 2008The multiwavelet property of Legendre wavelets is obtained by multiresolution analysis of multiplicity. Taking advantage of the translation property of Legendre wavelets, the extended Legendre wavelets, defined on the interval (-r, r), is achieved through a translation operator transformation on Legendre wavelets.

Abel inversion using Legendre wavelets expansion
Journal of Quantitative Spectroscopy and Radiative Transfer, 2007A new method is presented for reconstruction of the radially distributed emissivity from the line-of-sight projected intensity. The method is based on approximating the projected intensity profile by Legendre wavelets. The coefficients of the approximation are computed using the inner product of Legendre wavelets and the intensity profile.

Legendre wavelet for power amplifier linearization
Analog Integrated Circuits and Signal Processing, 2015Power amplifier (PA) plays a key role in transceivers for mobile communication systems and the improvement of the linearity of the PA becomes an objective of first importance. This paper proposes a novel linearization method for PA based on the Legendre wavelet possessing rich properties, so as to this technique combines the advantages of piecewise ...

Legendre wavelets direct method for variational problems
Mathematics and Computers in Simulation, 2000A direct method for solving variational problems using Legendre wavelets is presented. An operational matrix of integration is first introduced and is utilized to reduce a variational problem to the solution of algebraic equations. Illustrative examples are included to demonstrate the validity and applicability of the technique.

Extended Legendre Wavelets Neural Network
2008Based on analyzing Legendre wavelets, this paper presents the extended Legendre wavelets (ELW), which is defined on the interval (i¾? r,r), and proves to be orthogonal. Furthermore, this paper constructs the extended Legendre wavelet neural network (ELWNN) by using the ELW functions instead of the activation functions of a multilayer perceptron neural ...
