System and method for classifying signals using timing templates, power templates and other techniques

A radio device comprising:

• a. a radio transceiver that receives radio frequency energy in a radio frequency band in which radio signals of multiple types may be occurring;
• b. a Fast Fourier Transform (FFT) circuit coupled to the radio transceiver that converts received samples of the radio frequency energy into power versus frequency data comprising power levels for each of a plurality of frequency bins during an FFT interval;
• c. a spectrum analyzer circuit that is coupled to the FFT circuit that generates statistics from the power versus frequency data including at least one of an average power statistic for each frequency bin over a plurality of FFT intervals a maximum power statistic for each frequency bin over a plurality of FFT intervals;
• d. a plurality of pulse detectors that are coupled to receive the output of the FFT circuit, each of the pulse detectors being configurable to simultaneously detect signal pulses of radio frequency energy having signal pulse characteristics that fall within configurable ranges for at least one of center frequency, duration and bandwidth from the power versus frequency data, and output signal pulse data for pulses that meet the corresponding signal pulse characteristics;
• and
• e. a processor coupled to accumulate data output by the pulse detectors and the spectrum analyzer circuit and executing a plurality of classification procedures against-the accumulated data to identify signals occurring in the frequency band.
