Class-Specific Module module_bestkfft.m.
Consider the feature set consisting of
- The magnitude-squared values of the largest DFT bins in the bin range to .
- The bin indexes of the above largest DFT bins.
- The residual in-band energy in the bin range to (energy not contained in the largest bins).
- The total out-band energy (not in the bin range to ).
See module
software/module_bestkfft.m which implements this feature set,
function
software/module_bestkfft_synth.m which re-synthesizes the input data,
and
software/module_bestkfft_test.m for testing.
