DECODER WITH DETECTION AND CORRECTION OF ERRORS Russian patent published in 2009 - IPC H03M13/15 

FIELD: information technologies.

SUBSTANCE: invention is related to data transfer technology and may be used in systems with decision feedback for reception of information coded by cyclic code that permits majority decoding procedure. Decoder with detection and correction of errors comprises two OR elements, shift register, nine keys, syndrome calculator, summators, majority element, summator by module two, counter of corrections, shift counter, unit of discrete integration, counter of invalid symbols and buffer shift register. The novelty in decoder is introduction of discrete integration unit, counter of invalid symbols, the second OR element, two keys (eighth and ninth) and buffer shift register, and also change of connections between available elements of decoder. All that helped to increase noise immunity and accuracy of decoding of received discrete signals due to application of majority decoding principles.

EFFECT: improved noise immunity and accuracy of decoding.
