Sparse Bayesian Learning (SBL) Based Channel Estimation for Millimeter-Wave Hybrid Massive MIMO System

open access: yesInternational Journal of Intelligent Systems and Applications in Engineering
Reduced system complexity yields advantages that extend to enforcement obligations as well. The task of acquiring precise channel information for hybrid precoding in millimeter-wave (mmWave) systems is challenging for a multitude of reasons. Among the methods employed are analog precoding, a large number of antennas, and a pre-beamforming state with a ...

Fast estimation of array shape and direction of arrival using sparse Bayesian learning for manoeuvring towed line array

open access: yesIET Radar, Sonar & Navigation
The sparse Bayesian learning (SBL) algorithm has demonstrated its advantage in the direction of arrival (DOA) estimation. However, it requires a lot of computational cost to iteratively estimate the SBL hyperparameters from measurement data.
