A wavelet is a small localized wave based on a mathematical function. Wavelet analysis is able to represent signals in the time and frequency domains at the same time. Many modern applications have ...

Abstract: This study investigates a wavelet-aided orthogonal time-frequency space (W-OTFS) modulation system operating in low earth orbit (LEO) satellite systems. The discrete wavelet transform (DWT) ...

📌 Overview This project implements a chaos-based encryption technique combined with the Discrete Haar Wavelet Transform (DHWT) to securely encrypt an image and overlay it with another image. The ...

% for each trial in the 3D time-frequency arrays X and Y. % Inputs: % X - [M_X × T × N] complex, TF coefficients of signal X % Y - [M_Y × T × N] complex, TF coefficients of signal Y % in - [1 × M_X] ...

The Discrete Wavelet Transform (DWT) has gained the reputation of being a very effective signal analysis tool for many practical applications. This paper presents an approach towards VLSI ...

The experimental ultrasound data is always trained by measurement errors, internal and external noise. For this reason, it is always necessary to apply some signal processing operations, such as ...
