NOISE-IMMUNE DECODER COMPUTER Russian patent published in 2000 - IPC

FIELD: automatic control and computer engineering. SUBSTANCE: computer that may be found useful in building digital data transmission and processing hardware and in Reed-Solomon word decoders provides for combining procedures of locating error detector root polynomial and step-by-step method of decoding cyclic codes; each decoding step includes type-of-error classification, error location, and error computation procedures. Additional parity check character introduced in code word enables identification of situation in which invalid correction of three unrecoverable erroneous characters must be canceled. EFFECT: improved design. 3 dwg
