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 … WebIn order to meet practical requirements, the measurement matrix are generally expected to have the following properties: (1) The strong incoherence between measurement and sparse basis; (2) the number of measurements for perfect reconstruction is close to the theo-retical bound; (3) fast sampling and reconstruction; (4) low memory space and ... income tax ind as
