Title:
METHOD AND APPARATUS FOR ACQUIRING LINEAR PRECODER ON BASIS OF MACHINE LEARNING IN MULTI-USER MIMO WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/120864
Kind Code:
A1
Abstract:
The present disclosure relates to a method and an apparatus for acquiring a linear precoder on the basis of machine learning in a multi-user multiple input multiple output (MIMO) wireless communication system. A method by which a transmission end transmits a signal on the basis of a precoder in a multi-user MIMO wireless communication system, according to one embodiment of the present disclosure, comprises the steps of: acquiring a precoder by inputting channel information received from each of K (K is an integer greater than 0) reception ends into a trained precoder operation module; and transmitting a precoded signal to each of the K reception ends on the basis of the acquired precoder, wherein the precoder operation module can comprise a deep neural network to which a weight matrix W, a reception filter matrix U, and a normalization constant β are applied.
