FIELD: radio engineering. ^ SUBSTANCE: invention relates to electric communication and may be used in discrete data transmission systems. According to the invention, the method provides for generating data encoded with jam-proof short concatenated code or long concatenated code on the transmitting side. The decoding starts from the data encoded with an internal code of the long jam-proof concatenated code. In the place of internal code words that are not transmitted for the data encoded by the short jam-proof concatenated code, the blocked length of the accepted concatenated code is more precisely defined in the channel by comparing with known sequences taking into account data distortions, when phased and numbering sequences are removed during data reading from storage device. Based on the results of more qualitative words selection in the internal code, the optimal algorithm of the external code decoding is selected. ^ EFFECT: improved data reliability when working in real channels. |
