Abstract

A method for generating a data sample in a first frequency band from measurements in a second frequency band. The method includes obtaining a first plurality of samples, obtaining a second plurality of samples, obtaining a mapping model based on the first plurality of samples and the second plurality of samples, obtaining a third plurality of samples, and obtaining the data sample based on the mapping model and the third plurality of samples. Obtaining the first plurality of samples includes measuring a first frequency response of an environment in the first frequency band. Obtaining the second plurality of samples includes measuring a second frequency response of the environment in the second frequency band. Obtaining the third plurality of samples includes measuring a third frequency response of the environment in the second frequency band. Obtaining the data sample includes applying the mapping model on the third plurality of samples.
