Incoherence matrix
WebApr 1, 2024 · Given a matrix M ∈ M n 1 × n 2 ( R) of rank r, we say that M is μ 0 -incoherent if max ( μ ( U), μ ( V)) ≤ μ 0. Where here U and V are column and row space of M. Also, the strong incoherence of a matrix is the max of inner product between any two columns of … 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 …
