Title:
METHOD AND DEVICE FOR PREDICTING LOCATION USING ULTRA-WIDEBAND COMMUNICATION SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/080410
Kind Code:
A1
Abstract:
Disclosed is a method by which an electronic device predicts the location of a UWB signal. The method of the present disclosure may comprise the steps of: generating an input sequence from input data for a preset number of timesteps; generating an output sequence including prediction data for a next timestep from the input sequence using a trained RNN-based model; and obtaining information about a predicted location of the electronic device at the next timestep on the basis of the prediction data in the output sequence. The input data may include UWB DL-TDoA data.
