Abstract: For the research, the turbo-encoding method was chosen. It refers to the method of the direct correction of errors. We have implemented and studied programmatically the turbo-encoding and decoding systems, according to the method of maximum final probability. The model of a turbo-encoder is based on the use of the recursive systematic convolutional encoders and the use of interleaver for the connection of the encoders. We have implemented and calculated the decoding model by the method of maximum final probability using feedback and the decoder of the output hard decision. The simulated operation of the system was implemented in the hardware description language VHDL, which allows its implementation on the EPLD structures. The special features of the system turbo-encoding development in VHDL (Very high integrated circuits Hardware Description Language) include the possibility of using the system as a whole or partitioning the system into separate components. The turbo-encoding system can increase the speed of information transfer without requiring an increase of a transmitter power, or can be used to reduce the required power in the transmission with given rate. An important advantage of the system is an independence of the decoding complexity from the length of the information block that allows the reduction of the possibility of the decoding error by increasing its length
