WebApr 10, 2016 · The aim of this project publication is a comparative analysis of data hiding using two techniques: Discrete Wavelet Transform (DWT) and Stationary Wavelet Transform (SWT). WebThe signal from two sides of the transmission line will be applied to Wavelet transformation and noise filter algorithm for accurate calculation of the fault location. The result of this project has a pretty high precision and rarely depends on the others external factors so that it can widely apply to the real-life fault.
