Spectrum-blind minimum-rate sampling and reconstruction of multiband signals

  title={Spectrum-blind minimum-rate sampling and reconstruction of multiband signals},
  author={Ping Feng and Yoram Bresler},
We propose a universal sampling pattern and corresponding reconstruction algorithms that guarantee wellconditioned reconstruction of all multiband signals with a given spectral occupancy bound without prior knowledge of the spectral support. It is shown that such a universal sampling pattern can asymptotically achieve the Nyquist-Landau minimal sampling rate. Also, the new design method replaces the nonalising or packability criterion for a reconstructive sampling pattern with a more lenient… CONTINUE READING
