Signal source identification utilizing wavelet-based signal processing and associated method

A signal source identification system, comprising:

• a phase pre-processing sub-system coupled to receive an individual input signal stream, the phase pre-processing sub-system being configured to determine phase differential data for the individual input signal stream, the input signal stream corresponding to signal data from a signal source of unknown identity;
• a wavelet-based signal processing sub-system coupled to receive the phase differential data from the phase pre-processing sub-system, the wavelet-based signal processing sub-system being configured to apply wavelet packet processing to generate a signature for the individual input signal stream;
• a database having stored data, the stored data including wavelet-based signatures corresponding to known signal sources, known signal sources being signal sources that have been previously identified;
• and
• a signal source identification sub-system coupled to receive the signature from the wavelet-based signal processing sub-system, the signal source identification sub-system being configured to compare the signature for the input signal stream with the stored data and to determine if the individual input signal stream matches wavelet-based signatures of a known signal source in order to identify the input signal stream as being from a known signal source if a match is determined to be made, the signal source identification sub-system being further configured to output an indication of the identity of the signal source of the input signal stream.
