Recently, there has been a growing interest in estimation of sparse channels as they are observed in underwater acoustic and ultrawideband channels. In this paper we present a new Bayesian sparse channel estimation SCE algorithm that, unlike traditional SCE methods, exploits noise statistical information to improve the estimates. The proposed method uses approximate maximum a posteriori probability MAP to detect the non-zero channel tap locations while least square estimation is used to… Expand

Sparse Reconstruction Using Distribution Agnostic Bayesian Matching Pursuit
TLDR
A fast matching pursuit method using a Bayesian approach is introduced for sparse signal recovery and utilizes a priori statistics of additive noise and the sparsity rate of the signal, which are shown to be easily estimated from data if not available. Expand
