SYSTEM AND METHODS FOR DETERMINING MASKING SIGNALS FOR APPLYING EMPIRICAL MODE DECOMPOSITION (EMD) AND FOR DEMODULATING INTRINSIC MODE FUNCTIONS OBTAINED FROM APPLICATION OF EMD

A computer-implemented method of signal processing is provided. The method includes generating one or more masking signals based upon a computed Fourier transform of a received signal. The method further includes determining one or more intrinsic mode functions (IMFs) of the received signal by performing a masking-signal-based empirical mode decomposition (EMD) using the at least one masking signal.
