Xampling: Analog to Digital at Sub-Nyquist Rates
Moshe Mishali, Yonina C. Eldar, Oleg Dounaevsky +1
We present a sub-Nyquist analog-to-digital converter of wideband inputs. Our circuit realizes the recently proposed modulated wideband converter, which is a flexible platform for s…
Robust Recovery of Signals From a Structured Union of Subspaces
Yonina C. Eldar, Moshe Mishali
Traditional sampling theories consider the problem of reconstructing an unknown signal from a series of samples. A prevalent assumption which often guarantees recovery from the…
Reduce and Boost: Recovering Arbitrary Sets of Jointly Sparse Vectors
Moshe Mishali, Yonina C. Eldar
The rapid developing area of compressed sensing suggests that a sparse vector lying in an arbitrary high dimensional space can be accurately recovered from only a small set of non-…
Blind Multi-Band Signal Reconstruction: Compressed Sensing for Analog Signals
Moshe Mishali, Yonina C. Eldar
We address the problem of reconstructing a multi-band signal from its sub-Nyquist point-wise samples. To date, all reconstruction methods proposed for this class of signals assumed…
