Optimal Sampling and Reconstruction of Graph Signals in the Fractional Fourier Domain

Xiaopeng Cheng, Zhichao Zhang, Yangfan He

Graph signal sampling and reconstruction are commonly formulated in the graph Fourier transform (GFT) domain. However, the reconstruction performance may be limited when practical graph signals are not sufficiently concentrated in the GFT spectrum. To address this issue, this pap…Read more
