Title:
PARAMETER ESTIMATION METHOD AND APPARATUS BASED ON ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) SIGNAL, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016190
Kind Code:
A1
Abstract:
Provided in the present disclosure are a parameter estimation method and apparatus based on an orthogonal frequency division multiplexing (OFDM) signal, and a device. The method comprises: determining, according to a signal subspace matrix of an OFDM signal, a first reference matrix related to a first parameter of a target, wherein the signal subspace matrix comprises information related to at least one parameter; and determining the first parameter on the basis of a first reference feature value of the first reference matrix. By means of the present disclosure, the parameter acquisition cost of a target can be reduced, and the parameter sensing accuracy of the target can be effectively increased.
