Adaptive Q‐Wavelet Transform and Kalman Filtering for Power Quality Disturbance Prediction and Carbon Emission Impact Analysis in Smart Grids

Engineering Reports, Volume 8, Issue 5, May 2026.
Maintaining power quality (PQ) and minimizing carbon emissions are crucial for sustainable smart grids, especially with increasing renewable energy integration. This paper proposes a novel method combining Adaptive Q‐Wavelet Transform (AQWT) and Kalman Filtering (KF) to predict PQ disturbances and faults while analyzing their impact on carbon emissions.

Graph Fourier transform based on singular value decomposition of directed Laplacian

, 2022
Graph Fourier transform (GFT) is a fundamental concept in graph signal processing. In this paper, based on singular value decomposition of Laplacian, we introduce a novel definition of GFT on directed graphs, and use singular values of Laplacian to carry

Graph‐Based Spectrum Sensing via Quadratic Form of Adjacency Matrix

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This graphical abstract presents a graph‐signal‐processing‐based spectrum sensing algorithm for robust primary user detection at low signal‐to‐noise ratios (SNR). The observed signal is preprocessed via power spectrum calculation and block summation, and then transformed into a graph.
