Robust error correction for real-valued signals via message-passing decoding and spatial coupling
Jean Barbier, Florent Krzakala, Lenka Zdeborová +1
We revisit the error correction scheme of real-valued signals when the codeword is corrupted by gross errors on a fraction of entries and a small noise on all the entries. Combinin…

Compressed Sensing under Matrix Uncertainty: Optimum Thresholds and Robust Approximate Message Passing
Florent Krzakala, Marc Mézard, Lenka Zdeborová
In compressed sensing one measures sparse signals directly in a compressed form via a linear transform and then reconstructs the original signal. However, it is often the case that…
