Sparse signal recovery on the sphere: Optimizing the sensing matrix through sampling

Alem, Yibeltal; Chae, Daniel H; Kennedy, Rodney

Description

We propose a method for constructing a spherical harmonic sensing matrix that can be used to effectively recover a sparse signal on the sphere from limited measurements. For such a sensing matrix, in a compressed sensing setting, it is desirable that the
