Analysis of Democratic Voting Principles used in Distributed Greedy Algorithms
Dennis Sundman, Saikat Chatterjee, Mikael Skoglund
A key aspect for any greedy pursuit algorithm used in compressed sensing is a good support-set detection method. For distributed compressed sensing, we consider a setup where many…

Analysis of MMSE Estimation for Compressive Sensing of Block Sparse Signals
Mikko Vehkaperä, Saikat Chatterjee, Mikael Skoglund
Minimum mean square error (MMSE) estimation of block sparse signals from noisy linear measurements is considered. Unlike in the standard compressive sensing setup where the non-zer…
