Abstract

Abstract:

A compressive-domain filtering method based on oblique projector is proposed. The oblique projector used for filtering is constructed without exactly knowing the sparse positions of the target signals. It can eliminate the unwanted signal’s contribution to the measurements in compressive domain without first resorting to a full-scale reconstruction; meanwhile, it can preserve the information of target signal for reconstruction. Simulations show that this method can filter the unwanted signal effectively in compressive domain. Furthermore, and it is better than that of the filtering method based on orthogonal projector.

Key words: compressive sensing, compressive signal processing, oblique projector, filtering
