Structured random measurements in signal processing

Krahmer, Felix, Rauhut, Holger

Understand

Compressed sensing and its extensions have recently triggered interest in randomized signal acquisition.

  • A key finding is that random measurements provide sparse signal reconstruction guarantees for efficient and stable algorithms with a minimal number of samples.
  • While this was first shown for (unstructured) Gaussian random measurement matrices, applications require certain structure of the measurements leading to structured random measurement matrices.
  • Near optimal recovery guarantees for such structured measurements have been developed over the past years in a variety of contexts.
