METHOD OF JOINT ARITHMETIC AND IMMUNE CONSTRUCTION OF CODING AND DECODING Russian patent published in 2017 - IPC H03M13/07 H04L1/20 

FIELD: physics.

SUBSTANCE: in accordance to the invention for the next portion of the transmitted information sequence, the parity is selected, together arithmetically encoded, transmitted, formed of not more than the limiting number Z≥2 alternative received sequences and calculating the degree of similarity to the received sequence in a metric arithmetically decoded alternative received sequence is isolated more parts alternative reconstructed information sequence and alternative decoded parity and if the latter is valid, continuing the alternative received sequence of which is selected sequence with the lowest metric from which, with a predetermined decoding delay, the next part of the recovered information sequence is extracted, which is transmitted to the receiver.

EFFECT: joint arithmetic and noise-immune encoding and decoding of redundant binary information sequence, providing the possibility of practical implementation of correction of multiple transmission errors.
