Title:
LINEAR EQUALIZATION METHOD AND APPARATUS FOR ORTHOGONAL TIME FREQUENCY SPACE SYSTEM, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/042621
Kind Code:
A1
Abstract:
A linear equalization method and apparatus for an orthogonal time frequency space (OTFS) system, an electronic device for realizing the method, and a computer-readable storage medium. The method comprises: determining an effective channel matrix of an OTFS system in a delay-Doppler domain under a rectangular window limitation condition (202); determining a linear equalization estimation matrix according to the effective channel matrix (204); and equalizing received sampling signals according to the linear equalization estimation matrix (206).
