Parametrical channel estimation enables not only the expected large spectral efficiency in MIMO systems but also unveils relevant propagation parameters and allows low complexity representation of the channel matrix that facilitates massive deployments of antennas. In this work we propose to apply atomic norm as a gridless multidimensional spectral estimation approach to address parametrical channel estimation where both transmitter AoD and receiver AoA are identified. The proposed methodology is compared with several state of the art approaches based on grid recovery.

Abstract
Parametrical channel estimation enables not only the expected large spectral efficiency in MIMO systems but also unveils relevant propagation parameters and allows low complexity representation of the channel matrix that facilitates massive deployments of antennas. In this work we propose to apply atomic norm as a gridless multidimensional spectral estimation approach to address parametrical channel estimation where both transmitter AoD and receiver AoA are identified. The proposed methodology is compared with several state of the art approaches based on grid recovery.File | Dimensione | Formato | |
