Method And A System For Multiple Error Detection And Correction
US Patent:
4782490, Nov 1, 1988
Filed:
Mar 16, 1987
Appl. No.:
7/025978
Inventors:
Grigory Tenengolts - San Jose CA
Assignee:
Cythera Corporation - San Jose CA
International Classification:
C06F 1110
US Classification:
371 40
Abstract:
Disclosed is a method and a system for error detection and correction in which codewords are made up of data and two groups of check symbols. The first group of check symbols is generated by a correction verification code, which verifies error correction; and, the second group of check symbols is generated by an interleaved Reed-Solomon code with symbols from the Galois field GF(2. sup. 8), which serves for error correction. The correction verification code is cyclic with a generator polynomial g. sub. v (x)=x. sup. 2 +1 over the field GF(2. sup. 8). The Reed-Solomon code has a form g. sub. 0 (x)=x. sup. 4 +. alpha. sup. 54 x. sup. 3 +. alpha. sup. 9 x. sup. 2 +. alpha. sup. 54 x+1, where. alpha. is a primitive element of the field GF(2. sup.
