2021 ITU Kaleidoscope: Connecting Physical and Virtual Worlds (ITU K)(2021)
摘要
In this paper, we consider the problem of channel estimation for large scale Multiple-Input Multiple-Output (MIMO) systems, in which the main challenge that limits the functionality ofmassive MIMO is the acquisition of precise Channel State Information (CSI). We introduce an efficient channel estimation approach based on a block Sparse Bayesian Learning (SBL) that exploits the temporal common spar...
