Band-limited extrapolation on the sphere for signal reconstruction in the presence of noise

Alem, Yibeltal; Khalid, Zubair; Kennedy, Rodney


We investigate the problem of extrapolation of band-limited signals on the 2-sphere in the presence of noise. Specifically, given incomplete or spatially limited measurements subject to noise, find the unique extrapolation to the complete 2-sphere. We present an analytic solution to the extrapolation problem based on the expansion of a signal in Slepian basis corresponding to an orthogonal set of eigenfunctions of an associated energy concentration problem. An alternative equivalent iterative...[Show more]
