Sampling Order-Limited Signals on the Sphere
ICASSP 2023accepted
We formulate and generalize a sampling scheme on the sphere based on the Gauss-Legendre (GL) quadrature that permits the accurate computation of the spherical harmonic transform (SHT) and its inverse for the signals band-limited at L and order-limited at M using L(2M + 1) number of samples. Signals…
