ERROR-CORRECTING DECODER Russian patent published in 1996 - IPC

FIELD: computer engineering. SUBSTANCE: decoder has buffer storage unit 1, syndrome shaper 2, correction calculator 3, mode selector unit 4, locator generator 5, and adding unit 6. Biconditional implication units 8 and 9, adding unit 7, OR gate 10, and synchronizer 11 are introduced in decoder which ensures correction of one or two errors in code word or declines decoding in case of greater number of errors or no solution is found for selected generating polynomial over Galois field. EFFECT: improved speed of response, simplified design of decoders used in communication systems. 4 cl, 9 dwg, 4 tbl
