Mode-Tensorized Canonical Polyadic Decomposition for MIMO Channel Estimation
Alexander Blagodarnyi, Alexander Sherstobitov, Vladimir Lyashev
This paper proposes a channel estimation method for Multiple-Input Multiple-Output (MIMO) systems based on Canonical Polyadic (CP) decomposition applied to a mode-factorized tensor…
