Abstract
Embodiments of the present invention relate to ultrasound (acoustic) data transmission systems, in particular data transmission over wide-band acoustic channels with frequency-dependant multi-path propagation. More specifically, embodiments of the invention involve increasing the bit rate in the acoustic channel by means of utilization of the entire ultrasound spectrum available for data transmission inside a human body.
Claims10
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.
