Fast bayesian matching pursuit
WebRegarding the complexities for Bayesian estimation, the fast implementation is also studied, where the stop condition for the proposed iterative algorithm is also optimized. … 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

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 ... 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. This method performs sparse signal estimation via model selection and
