Application of the Wavelet Transform with a Piecewise Linear Basis to the Evaluation of the Hankel Transform
Peter S. Zykov, Eugene B. Postnikov · arXiv (Cornell University) · 2004
A method for computing the Hankel transform is proposed whereby the letter is reduced to a sum by representing the integrand as a smooth function times a Bessel function. The smooth function is replaced by its wavelet decomposition with a basis such that its scalar product with the Bessel function is calculated analytically. The result is represented as a series, with the coefficients strongly depending on the local behavior of the function being transformed. The application of the method is demonstrated by an example illustrated with plots.
