METHOD OF DISCRETE INFORMATION TRANSFER Russian patent published in 2009 - IPC H03M7/06 

FIELD: information technologies.

SUBSTANCE: in method of discrete information transfer on transmitting side at every cycle initial binary symbols with application of three channels are transformed into three-digit combinations, which carry information on criterion of current binary symbol in block of zeros or block of units (criterion of unit, zero or symbol repetition in block), zeros in combination define channels locked in this cycle; at every cycle in unlocked channel carrying oscillation is modulated, for every channel modulation parameters differ from each other by value; on receiving side signal is demodulated, and at every cycle transmitted combination of binary symbols is restored; permitted combinations of ternary code are formed, elements of which are elements from Galois field GF(3); if errors are detected in combination, symbol of ternary code current symbol erasure is generated, if there is no error, then symbol of ternary code is generated, which corresponds to criterion of current binary symbol; correction of average erased symbols is done in those combinations of ternary code, where all three symbols are different; in accepted combinations of ternary code binary symbols are restored; symbols of ternary code combinations that correspond to repletion criterion are transformed into binary symbols and used for synchronisation of reception process.

EFFECT: increase of noise immunity and elimination of permanent component in signal.
