Dynamic Compressive Sensing of Time-Varying Signals Via Approximate Message Passing

  title={Dynamic Compressive Sensing of Time-Varying Signals Via Approximate Message Passing},
  author={Justin Ziniel and Philip Schniter},
  journal={IEEE Transactions on Signal Processing},
In this work the dynamic compressive sensing (CS) problem of recovering sparse, correlated, time-varying signals from sub-Nyquist, non-adaptive, linear measurements is explored from a Bayesian perspective. While there has been a handful of previously proposed Bayesian dynamic CS algorithms in the literature, the ability to perform inference on high-dimensional problems in a computationally efficient manner remains elusive. In response, we propose a probabilistic dynamic CS signal model that… CONTINUE READING
