FIELD: discrete information transmission.
SUBSTANCE: in the method of stable code cyclic synchronization when using hard and soft solutions and modulation according to the C1-FL junction type, modified information of the C1-FL junction type is received from the channel from the channel. The correction device for each bit of modulated information calculates its quality, according to which the signs are formed least reliable bits, and error vectors are formed for these least reliable bits. Error vectors, summed modulo two with the input bipulse information, enter the block of demodulators, at the outputs of which the bits of BCH words and words formed at the junctions of BCH words are formed. Next, these words enter the Huffman filter block to further determine the endings of the blocks. From the correction device, a bipulse sequence corresponding to the modulated information of the C1-FL junction type, the quality of its bits, and the signs of the least reliable bits, so that there is no loss, are written to the information storage device through a register that takes into account processing delays in the demodulator, the error vector generation circuit and the Huffman filter bank.
EFFECT: technical result is to ensure high reliability of the received information, while ensuring high speed of information transmission and simple circuit design.
