Abstract

We approach the problem of sub-Nyquist sampling of multidimensional, multiband signals, with known spectral support that does not necessarily tile RN under translation. Undersampling is achieved by adapting the Papoulis' multichannel sampling scheme. Minimum (Landau) sampling density is obtained in some special conditions.
