1. A method of demodulating acoustic data, comprising:

  • receiving a wide-band acoustic data signal;

    transforming the wide-band acoustic data signal into a plurality of frequency-divided sub-band signals, wherein the plurality of frequency-divided sub-band signals are modulated with a plurality of modulation schemes;

    generating a plurality of data streams by demodulating each sub-band signal in the plurality of frequency-divided sub-band signals into a data stream according to a respective frequency band and demodulation scheme, each data stream in the plurality of data streams corresponding to one of the plurality of frequency-divided sub-band signals; and

    combining the plurality of data streams into an output data stream.
