COMPRESSIVE SAMPLING OF PHYSIOLOGICAL SIGNALS USING TIME-FREQUENCY DICTIONARIES BASED ON MODULATED DISCRETE PROLATE SPHEROIDAL SEQUENCES

摘要

A method of sampling and reconstructing an original physiological signal obtained from a subject includes acquiring a number of samples of the original physiological signal, and generating a reconstructed physiological signal using the samples and a time-frequency dictionary, the time-frequency dictionary having bases which are modulated discrete prolate spheroidal sequences.
