Abstract:
In this paper, we derive a mathematically equivalent frequency-domain relation between uniform and bunched nonuniform samples. This relation aids in the reconstruction of uniform samples, obtained from nonuniform samples, using a uniform discrete Fourier transform (DFT) modulated filter bank. We consider a general case of unequal spacing between the bunches of nonuniform samples. Simulation results demonstrate the practical utility of the theory proposed.
