Incoherence compressed sensing
WebJul 1, 2011 · Introduction Compressed sensing is a new data acquisition theory based on the discovery that one can exploit sparsity or compress- ility when acquiring signals of general interest, and that one can design nonadaptive sampling techniques that condense e information in a compressible signal into a small amount of data [13,16,18]. Web1 day ago · Abstract. Compressive Sensing (CS) theory has been used for Synthetic Aperture Radar (SAR) imaging due to the sparsity feature of SAR images. Therefore, some well-known CS algorithms like Orthogonal Matching Pursuit (OMP) and Regularized OMP (ROMP) methods have been employed for SAR image formation with a very small number …

Web2 I. INTRODUCTION MULTUIPLE measurement vector (MMV) problem [1]–[3], also known as joint sparse recovery in compressed sensing (CS) [4], [5], aims to jointly reconstruct the sparse signal matrix X ∈ RN×E from the matrix Y ∈ RM×E that contains multiple measurement vectors: Y = DX+N, (1) based on the measurement matrix D ∈ RM×N with M … Webincoherence are actually desirable in practice, even in applications where there is flexibility to design sensing operators with this property (for example, in compressive imaging). Our theorems show that asymptotically incoherent sensing and multilevel sampling allow one to exploit asymptotic, as opposed to just global sparsity.
