BEAM FORMING PREDICTING DEVICE, METHOD, AND PROGRAM

Title:

BEAM FORMING PREDICTING DEVICE, METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2022/034692

Kind Code:

A1

Abstract:

The objective of the present disclosure is to perform beam forming corresponding to the effects of a dynamic environment through which a user moves.　The present disclosure provides a beam forming predicting device provided with: a storage unit which stores a fingerprint database based on trajectories, and on a dictionary D obtained by learning fingerprints based on the trajectories; a trajectory predicting unit which uses position information of a mobile terminal to calculate the trajectory of the mobile terminal; a fingerprint estimating unit which applies the trajectory of the mobile terminal to the input of the dictionary D to calculate a sparse coefficient X corresponding to the trajectory of the mobile terminal; and a beam forming calculating unit which uses the sparse coefficient X calculated by the fingerprint estimating unit, and the fingerprint database, to calculate beam forming for the mobile terminal.
