A Missing Data Recovery Method of Sparse Graph Signal in GFT Domain

2018

In this paper, a missing data recovery method of sparse graph signal in graph Fourier transform (GFT) domain is presented. First, K-sparse graph signal which only has K non-zero elements in GFT domain is defined. …

Least Squares, Minimax and Peak Constrained Designs of Polynomial Hypergraph Filters

2022 · 2022 IEEE 65th International Midwest Symposium on Circuits and Systems (MWSCAS)

In this paper, the polynomial hypergraph filter (PHF) designs using least squares, minimax and peak constrained methods are presented. First, the hypergraph Laplacian matrix (HLM) is used to define the hypergraph Fourier transform (HFT) by …
