CHIRRUP: a practical algorithm for unsourced multiple access
Robert Calderbank, Andrew Thompson
Unsourced multiple access abstracts grantless simultaneous communication of a large number of devices (messages) each of which transmits (is transmitted) infrequently. It provides…
Sketching for Sequential Change-Point Detection
Yang Cao, Andrew Thompson, Meng Wang +1
We study sequential change-point detection procedures based on linear sketches of high-dimensional signal vectors using generalized likelihood ratio (GLR) statistics. The GLR stati…
Data Representation using the Weyl Transform
Qiang Qiu, Andrew Thompson, Robert Calderbank +1
The Weyl transform is introduced as a rich framework for data representation. Transform coefficients are connected to the Walsh-Hadamard transform of multiscale autocorrelations, a…
On block coherence of frames
Robert Calderbank, Andrew Thompson, Yao Xie
Block coherence of matrices plays an important role in analyzing the performance of block compressed sensing recovery algorithms (Bajwa and Mixon, 2012). In this paper, we characte…
An exact tree projection algorithm for wavelets
Coralia Cartis, Andrew Thompson
We propose a dynamic programming algorithm for projection onto wavelet tree structures. In contrast to other recently proposed algorithms which only give approximate tree projectio…
