METHOD OF JOINT ARITHMETIC AND PROTECTIVE CODING (VERSIONS) Russian patent published in 2017 - IPC H04M13/00 H03M13/00 

FIELD: information technology.

SUBSTANCE: check symbols on transmitting side are selected by allocation of a sub-interval for each check symbol among current zero symbol encoding sub-interval and current single symbol encoding sub-interval, including the middle of initial interval of arithmetic coding, and check symbols sets the symbol corresponding to the selected current sub-interval, next part of encoded sequence is transmitted on the receiving side, wherein, if the current decoding subinterval of each decoded check symbols includes the middle of initial interval of arithmetic coding, the absence of transmission errors is concluded.

EFFECT: joint arithmetic and noise protective coding of redundant binary information sequence providing reduction in requirements for transmission speed of encoded sequence through transmission channel and reduction in capacity of devices for its storage.
