Shift-invariant spaces on finite undirected graphs
Yang Chen, Seok-Young Chung, Qiyu Sun
Shift-invariant spaces (SISs) on the real line provide a natural framework for representing, analyzing and processing signals with inherent shift-invariant structure. In this paper…
Kalman Filtering of Stationary Graph Signals
Yang Chen, Yeonju Lee, Yao Shi +1
In this paper, we propose a novel definition of stationary graph signals, formulated with respect to a symmetric graph shift, such as the graph Laplacian. We show that stationary g…
Conjugate phase retrieval in shift-invariant spaces generated by a Gaussian
Yang Chen, Cheng Cheng
Conjugate phase retrieval considers the recovery of a function, up to a unimodular constant and conjugation, from its phaseless measurements. In this paper, we explore the conjugat…
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…
Graph Fourier transform based on singular value decomposition of directed Laplacian
Yang Chen, Cheng Cheng, Qiyu Sun
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 definitio…
Phase retrieval of complex and vector-valued functions
Yang Chen, Cheng Cheng, Qiyu Sun
The phase retrieval problem in the classical setting is to reconstruct real/complex functions from the magnitudes of their Fourier/frame measurements. In this paper, we consider a…
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…
Spectra of Bochner-Riesz means on
Yang Chen, Qiquan Fang, Qiyu Sun
The Bochner-Riesz means are shown to have either the unit interval or the whole complex plane as their spectra on
Reconstruction of sparse wavelet signals from partial Fourier measurements
Yang Chen, Cheng Cheng, Qiyu Sun
In this paper, we show that high-dimensional sparse wavelet signals of finite levels can be constructed from their partial Fourier measurements on a deterministic sampling set with…
