N2 - Sub-Nyquist systems capture the signal information in a different fashion than uniform high-rate samples. Consequently, digital processing, which is the prime reason for leaving the analog domain, becomes challenging. We propose a digital algorithm that translates samples obtained by the modulated wideband converter, a recent sub-Nyquist system, to the standard format of existing software packages. Our algorithm works in baseband, that is without the need to interpolate the samples to the Nyquist grid. Related methods such as nonuniform sampling or the random demodulator are shown to lack the baseband processing option.
