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…
A null space analysis of the L1 synthesis method in dictionary-based compressed sensing
Xuemei Chen, Haichao Wang, Rongrong Wang
An interesting topic in compressed sensing aims to recover signals with sparse representations in a dictionary. Recently the performance of the L1-analysis method has been a focus,…
Accurate detection of moving targets via random sensor arrays and Kerdock codes
Thomas Strohmer, Haichao Wang
The detection and parameter estimation of moving targets is one of the most important tasks in radar. Arrays of randomly distributed antennas have been popular for this purpose for…
Uncertainty Principles in Finitely generated Shift-Invariant Spaces with additional invariance
Romain Tessera, Haichao Wang
We consider finitely generated shift-invariant spaces (SIS) with additional invariance in . We prove that if the generators and their translates form a frame, then they…
Uncertainty Principles and Balian-Low type Theorems in Principal Shift-Invariant Spaces
Akram Aldroubi, Qiyu Sun, Haichao Wang
In this paper, we consider the time-frequency localization of the generator of a principal shift-invariant space on the real line which has additional shift-invariance. We prove th…
Sequential adaptive compressed sampling via Huffman codes
Akram Aldroubi, Haichao Wang, Kourosh Zarringhalam
There are two main approaches in compressed sensing: the geometric approach and the combinatorial approach. In this paper we introduce an information theoretic approach and use res…
