Fast bayesian matching pursuit
WebOct 14, 2024 · Fast Bayesian matching pursuit (FBMP) [14] is a hybrid of MP and Bayesian algorithm that assumes a Bernoulli-Gaussian prior on the non-zero entries yet is solved through greedy search. Moreover, different from previous Bayesian algorithms, FBMP takes into full consideration the uncertainty of the estimation and learns the … WebSep 1, 2024 · Then, based on the prior probability and equivalent sensing matrix, a selection metric is defined to select the block index into the dominant support by exploiting the …

WebBayesian compressed sensing (BCS) [8], as a special form of CS, has better performance than the traditional CS algo-rithms in many applications by using the statistics of sparse signal as a priori knowledge. In this paper, we investigate UWA channel estimation based on fast Bayesian matching pursuit (FBMP) [9]. In UWA WebAnother straightforward tree-search also appears in Fast Bayesian Matching Pursuit [17], which opens all children of the nodes at a level, and retains the best D wrt. their posterior probabilities. These methods incorporate rather simple and non-sophisticated tree-search techniques in comparison to A*OMP.
WebRecently, in order to make use of the statistic property of noise and signal, some matching pursuit methods that based on statistic prior information have been proposed, such as fast Bayesian matching pursuit (FBMP) method which utilises the prior distribution of noise and signal to seek the maximum a posterior (MAP) estimation of the sparse ... http://www.erdogan.org/publications/karahanoglu12aom.pdf
WebAnother category of methods based on the Bayesian ap-proach considers complete a priori statistical information of sparse signals. A method called fast Bayesian matching pursuit (FBMP) [9], adopts such an approach and assumes a Gaussian prior on the unknown sparse vector, x.
