Résumé:
This paper addresses the multi-source localization
problem by utilizing a novel subspace based joint sparse recovery
approach. We firstly introduce a multiple measurement vector
(MMV) positioning framework in the context of joint sparse
recovery. To sufficiently degrade the effect of measurement noise
at a lower cost of deployed anchors, we then optimally hybridize
the compressive sensing and array signal processing so that a
part of location supports are first identified by CS scheme and
the remaining supports are determined by a generalized subspace
criterion. Meanwhile, we design a post refined procedure to
further improve the estimate accuracy by considering the grid
assumption. Finally, a comprehensive set of simulations had been
conducted to demonstrate the
