Sparse Bayesian learning-based massive multi-user detection algorithm [PDF]
Aiming at the problem that most existing algorithms were based on the Gaussian inverse gamma prior model (GIG-SBL), which ignored the sparsity of the support set vector within the sparse solution, a sparse Bayesian learning framework based on the ...

Complex Multisnapshot Sparse Bayesian Learning for Offgrid DOA Estimation
Direction of arrival (DOA) estimation has recently been developed based on sparse signal reconstruction (SSR). Sparse Bayesian learning (SBL) is a typical method of SSR.

Abstract Hybrid precoding in millimeter-wave large MIMO systems is a critical component for lowering radio-frequency hardware costs as compared to the traditional fulldigital precoding strategy. Knowledge of channels is required for hybrid precoding. Though, estimation of the channel is problematic for the mm-Wave system because of the usage of

Spatiotemporal local changes have been extracted for evaluating physiological phenomena by an image reconstruction algorithm of electrical impedance tomography (EIT) using sparse Bayesian learning (SBL). The proposed method identifies a region of interest (ROI) by a priori information on conductivity distribution σ of each biological tissue and ...

Frequency Analysis of Acoustic Data Using Multiple-Measurement Sparse Bayesian Learning
Passive sonar systems are used to detect the acoustic signals that are radiated from marine objects (e.g., surface ships, submarines, etc.), and an accurate estimation of the frequency components is crucial to the target detection.

Identification of nonlinear sparse networks using sparse Bayesian learning [PDF]
© 2017 IEEE. This paper considers a parametric approach to infer sparse networks described by nonlinear ARX models, with linear ARX treated as a special case. The proposed method infers both the Boolean structure and the internal dynamics of the network.
