Abstract
We give a new deterministic construction of integer sensing matrices that can be used for the recovery of integer-valued signals in compressed sensing. This is a family of integer matrices, , with bounded sup-norm and the property that no column vectors are linearly dependent, . Further, if then as . Our construction comes from particular sets of difference vectors of point-sets in that cannot be covered by few parallel hyperplanes. We construct examples of such sets on the grid and use them for the matrix construction. We also show a connection of our constructions to a simple version of the Tarski plank problem.
