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.

A method by an electronic device using ultra-wideband (UWB) communication, the method comprising:
- generating an input sequence from input data for a preset number of timesteps, the input data including UWB downlink time difference of arrival (DL-TDoA) data;
- generating an output sequence including prediction data for a next timestep from the input sequence using a trained recurrent neural network (RNN)-based model;
- and
- obtaining information about a predicted location of the electronic device at the next timestep based on the prediction data in the output sequence.
An electronic device using ultra-wideband (UWB) communication, comprising:
