Title:
WIRELESS POSITIONING PARAMETER ESTIMATION METHOD, APPARATUS AND SYSTEM, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/000614
Kind Code:
A1
Abstract:
The present application relates to a wireless positioning parameter estimation method and apparatus, a computer device, a system, and a storage medium. The method comprises: performing channel estimation on a positioning signal sent by a device to be positioned, so as to obtain a channel response parameter; performing delay domain super-resolution spectrum estimation on the channel response parameter to obtain delay domain super-resolution spectrum information; and performing spatial spectrum estimation on the delay domain super-resolution spectrum information to obtain delay domain super-resolution spectrum-spatial spectrum information; and then obtaining corresponding positioning parameter estimation values of transmission paths from the delay domain super-resolution spectrum-spatial spectrum information.
