Abstract
This paper proposes M-channel oversampled filter banks for graph signals. The filter set satisfies the perfect reconstruction condition. A method of designing oversampled graph filter banks is presented which allows us to design filters with arbitrary parameters, unlike the conventional critically-sampled graph filter banks. The practical performance of the proposed filter banks is validated through graph signal denoising experiments.
