Abstract

This paper introduces the Reed Muller Sieve, a deterministic measurement matrix for compressed sensing. The columns of this matrix are obtained by exponentiating codewords in the quaternary second order Reed Muller code of length NN. For k=O(N)k=O(N), the Reed Muller Sieve improves upon prior methods for identifying the support of a kk-sparse vector by removing the requirement that the signal entries be independent. The Sieve also enables local detection; an algorithm is presented with complexity N2logNN^2 \log N that detects the presence or absence of a signal at any given position in the data domain without explicitly reconstructing the entire signal. Reconstruction is shown to be resilient to noise in both the measurement and data domains; the 2/2\ell_2 / \ell_2 error bounds derived in this paper are tighter than the 2/1\ell_2 / \ell_1 bounds arising from random ensembles and the 1/1\ell_1 /\ell_1 bounds arising from expander-based ensembles.
