Iterative method to compute the maximal concentration Slepian band-limited eigenfunction on the sphere

Khalid, Zubair; Kennedy, Rodney

Description

The Slepian concentration problem on the sphere to maximize the energy concentration of a band-limited (in spherical harmonic degree) function is formulated as an eigenvalue problem, the solution of which gives rise to a family of band-limited eigenfunctions with optimal energy concentration in the spatial region on the sphere. In the family of band-limited eigenfunctions, the most concentrated (in the spatial region) eigenfunction is used for spatial windowing and spatial smoothing. We develop...[Show more]
