Model based variational Bayesian compressive sensing using heavy tailed sparse prior
作者:
Highlights:
• We have proposed a new model based Bayesian Compressive Sensing (CS) based on generalized double Pareto.
• We have derived all posterior pdfs׳ parameters of this new model in the closed form.
• We examine the proposed algorithm in two scenarios: without noise and noisy observation.
• In both scenarios, the proposed algorithm outperforms the well-known CS method.
