Zero-forcing and MMSE filters design on the 2-sphere

Wei, Liying; Kennedy, Rodney


We design a zero-forcing filter and a minimum mean square error (MMSE) filter on the 2-sphere by a spherical harmonic multiplication operator. Compared with the traditional optimal filters, our filters, determined by the signal and noise statistics, have
