Time-Modulated Arrays With Haar Wavelets [PDF]
IEEE Antennas and Wireless Propagation Letters, 2020 Time-modulated arrays (TMAs) can effectively perform beamsteering over the first positive harmonic pattern by applying progressively delayed versions of stair-step approximations of a sine waveform to the antenna excitations. In this letter, we consider synthesizing such stair-step sine approximations by means of Haar wavelets.

Multiresolution Analysis and Haar Wavelets on the Laguerre Hypergroup [PDF]
Mathematical Problems in Engineering, 2009 Let ℍn be the Heisenberg group. The fundamental manifold of the radial function space for ℍn can be denoted by [0, +∞) × ℝ, which is just the Laguerre hypergroup. In this paper the multiresolution analysis on the Laguerre hypergroup 𝕂 = [0, +∞) × ℝ is defined. Moreover the properties of Haar wavelet bases for are investigated.

The Haar wavelet characterization of weighted Herz spaces and greediness of the Haar wavelet basis
Journal of Mathematical Analysis and Applications, 2010 The authors study the class of dyadic \(A_p\)-weights in connection with dyadic maximal operators (where in both cases on considers dyadic cubes only) and show that one obtains results corresponding to the ones one gets for the usual \(A_p\)-weights and maximal operators.

Mixed Problem for Partial Differential Equation of Large Time Variable Order
Journal of Optimization, Differential Equations and Their ApplicationsAn algorithm for solving a class of linear variable order fractional partial differential equations (FPDEs) is presented in this paper. We utilized a combination of Caputo fractional derivatives with the Haar wavelet collocation method (HWCM) and Eiler ...

Simulation of a non‐linear, time‐variant circuit using the Haar wavelet transform
IET Science, Measurement & Technology, 2022 Wavelet theory has disentangled numerous complexities, including those pertinent to transient and steady‐state responses of systems, when Laplace and Fourier transforms face insoluble obstacles. Reactive linear components (e.g.

Signal Estimation Using Wavelet Analysis of Solution Monitoring Data for Nuclear Safeguards
Axioms, 2013 Wavelets are explored as a data smoothing (or de-noising) option for solution monitoring data in nuclear safeguards. In wavelet-smoothed data, the Gibbs phenomenon can obscure important data features that may be of interest.
