Graph Fourier transforms on directed product graphs
Cheng Cheng, Yang Chen, Jeon Yu Lee +1
Graph Fourier transform (GFT) is one of the fundamental tools in graph signal processing to decompose graph signals into different frequency components and to represent graph signa…
Preconditioned Gradient Descent Algorithm for Inverse Filtering on Spatially Distributed Networks
Cheng Cheng, Nazar Emirov, Qiyu Sun
Graph filters and their inverses have been widely used in denoising, smoothing, sampling, interpolating and learning. Implementation of an inverse filtering procedure on spatially…
Stable Phase Retrieval from Locally Stable and Conditionally Connected Measurements
Cheng Cheng, Ingrid Daubechies, Nadav Dym +1
This paper is concerned with stable phase retrieval for a family of phase retrieval models we name "locally stable and conditionally connected" (LSCC) measurement schemes. For ever…
Stable Phaseless Sampling and Reconstruction of Real-Valued Signals with Finite Rate of Innovations
Cheng Cheng, Qiyu Sun
A spatial signal is defined by its evaluations on the whole domain. In this paper, we consider stable reconstruction of real-valued signals with finite rate of innovations (FRI), u…
Nonsubsampled Graph Filter Banks and Distributed Implementation
Junzheng Jiang, Cheng Cheng, Qiyu Sun
In this paper, we consider nonsubsampled graph filter banks (NSGFBs) to process data on a graph in a distributed manner. Given an analysis filter bank with small bandwidth, we prop…
Phase Retrieval of Real-Valued Signals in a Shift-Invariant Space
Yang Chen, Cheng Cheng, Qiyu Sun +1
Phase retrieval arises in various fields of science and engineering and it is well studied in a finite-dimensional setting. In this paper, we consider an infinite-dimensional phase…
