Abstract: A method for generating at least one of a plurality of data samples in a first frequency band from measurements in a second frequency band. The method includes obtaining a first plurality of samples by measuring a plurality of frequency responses of an environment in the first frequency band, obtaining a second plurality of samples by measuring a first set of frequency responses of the environment in the second frequency band, obtaining a mapping model based on the first plurality of samples and the second plurality of samples, obtaining a third plurality of samples by measuring a second set of frequency responses of the environment in the second frequency band, and obtaining the at least one of the plurality of data samples by applying the mapping model on the third plurality of samples.
