METHOD FOR COMBINED COMPRESSION AND NOISELESS CODING Russian patent published in 2016 - IPC H03M13/00 

FIELD: telecommunications.

SUBSTANCE: invention relates to communication and can be used in data exchange via transmission channels with errors. For this purpose at the transmission next part of an information sequence is obtained, check symbols are calculated from it, which are recorded together with the next part of the information sequence into the next part of the noiseless sequence, which is compressed and transmitted, at the receiving the next part of the received sequence is obtained, which is saved and then the saved next parts of the received sequence are decompressed into next parts of the decoded sequence, from which next parts of the restored information sequence and decoded check symbols are identified, from the next part of the restored information sequence check symbols are calculated, which are compared bitwise with the decoded check symbols and in case of their bitwise coincidence the conclusion is made upon absence of transmission errors, in case of non-coincidence - one or more bits in the saved next parts of the received sequence are alternately inverted, which are decompressed, and subsequently the next actions are performed until reaching the output on the absence of transmission errors.

EFFECT: technical result is higher accuracy of detecting and correcting transmission errors.
