Adaptive blind source separator for ultra-wide bandwidth signal tracking

A computer program product for blind source separation, the computer program product comprising:

• a non-transitory computer-readable medium having executable instructions encoded thereon, such that upon execution of the instructions by one or more processors, the one or more processors perform operations of:
• continuously passing a time-series of data points from one or more mixtures of source signals through a plurality of adaptable filters having center frequencies, resulting in a plurality of output signals, each filter in the plurality of adaptable filters having a corresponding output signal;
• determining an error of each output signal, resulting in a set of error signals;
• determining a filter state of each filter using the error signals, resulting in a set of filter states;
• adapting a set of filter center frequencies with a filter center frequency adapter by receiving and using both the set of error signals and the set of filter states, resulting in new filter center frequencies;
• updating the set of filter center frequencies with the new filter center frequencies;
• and
• extracting separated source signals from the mixture of signals.

A computer implemented method for blind source separation, the method comprising an act of:

• causing one or more processors to execute instructions encoded on a non-transitory computer-readable medium, such that upon execution, the one or more processors perform operations of:
• continuously passing a time-series of data points from one or more mixtures of source signals through a plurality of adaptable filters having center frequencies, resulting in a plurality of output signals, each filter in the plurality of adaptable filters having a corresponding output signal;
• determining an error of each output signal, resulting in a set of error signals;
• determining a filter state of each filter using the error signals, resulting in a set of filter states;
• adapting a set of filter center frequencies with a filter center frequency adapter by receiving and using both the set of error signals and the set of filter states, resulting in new filter center frequencies;
• updating the set of filter center frequencies with the new filter center frequencies;
• and
• extracting separated source signals from the mixture of signals.
