METHOD, SYSTEM AND DEVICE FOR MODULATION MODE SELF-ADAPTATION AND ELECTRONIC SIGNATURE TOKEN Russian patent published in 2017 - IPC H04L27/00 

FIELD: electronics.

SUBSTANCE: invention relates to electronic engineering and intended to determine audio modulation mode, for fast data interaction by audio messages modulation mode self-adaptation. Invention discloses,in particular, method of audio messages modulation mode self-adaptation, which comprises following stags: first device modulates first audio data using, at least, two modulation modes to generate first streams of audio data frames and merges them into audio data first stream for sending to second device; second device determines modulation modes based on audio data first stream, correctly received and supported by first device; second audio data modulation by means of, at least, two modulation modes, correctly received and supported by first device to generate audio data frames second streams, their merging into audio data second stream for sending to first device; first device determines modulation modes based on audio data first stream, correctly received and supported by second device; and first device selects optimal modulation mode and modulation mode, used by second device.

EFFECT: determination of audio modulation mode, for fast data interaction by audio messages modulation mode self-adaptation.
