Line Spectrum Estimation with Probabilistic Priors
Dave Zachariah, Petter Wirfält, Magnus Jansson +1
For line spectrum estimation, we derive the maximum a posteriori probability estimator where prior knowledge of frequencies is modeled probabilistically. Since the spectrum is peri…
Distributed Greedy Pursuit Algorithms
Dennis Sundman, Saikat Chatterjee, Mikael Skoglund
For compressed sensing over arbitrarily connected networks, we consider the problem of estimating underlying sparse signals in a distributed manner. We introduce a new signal model…
Statistical Mechanics Approach to Sparse Noise Denoising
Mikko Vehkapera, Yoshiyuki Kabashima, Saikat Chatterjee
Reconstruction fidelity of sparse signals contaminated by sparse noise is considered. Statistical mechanics inspired tools are used to show that the l1-norm based convex optimizati…
