Abstract:
This specification covers a simplified and high speed decoding scheme for Reed-Solomon codes capable of correcting up to three symbol errors in code words made up of k data and n-k check symbols where each symbol consists of m binary bits of information. In such a code the error location polynomial. sigma. (x) = x. sup. e +. sigma. sub. 1 x. sup. e-1. . . . . sigma. sub. e where e equals the number of symbol errors and the coefficient of. sigma. (x) are related to the error syndromes S. sub. i by the equation S. sub. i+e +. sigma. sub. 1 S. sub. i+e-1 +. . . . +. sigma. sub. e-1 S. sub. i+1 +. sigma. sub. e S. sub. i = 0. The decoder first tests if S. sub. 0 = 0. If S. sub. 0. noteq. 0, the assumption is made that a single symbol error has occurred. The decoder quickly verifies this by determining if S. sub. 2 +. sigma. S. sub.

Abstract:
A modularized error correction apparatus for correcting package errors is provided by expanding an N bit single error correction, double error detection code to cover N packages of M bits each, so that the Exclusive-OR of all M bit single bit error syndromes in any given package results in a composite syndrome which is unique for each package. See FIG. 2 for the parity matrix H and the matching matrix M for the error correction code.

Abstract:
This specification describes a convolutional code and apparatus for the correction of errors in differentially encoded quadrature phase shift keyed data (DQPSK). In each sequence of forty bits 24 are information bits and the remainder are parity bits. Two parity bits are generated for each three information bit set in the sequence in accordance with the following equations: P. sub. 8. sup. a = i. sub. 8. sup. a. sym. i. sub. 8. sup. b. sym. i. sub. 6. sup. b. sym. i. sub. 1. sup. b. sym. i. sub. 3. sup. c. sym. i. sub. 2. sup. c P. sub. 8. sup. b = i. sub. 8. sup. a. sym. i. sub. 6. sup. a. sym. i. sub. 3. sup. a. sym. i. sub. 5. sup. b. sym. i. sub. 8. sup. c. sym. i. sub. 4. sup. c where i. sub. 8. sup. a, i. sub. 8. sup. b and i. sub. 8. sup. c are the three information bits in the set associated with the parity bits P. sub. 8. sup. a and P. sub. 8. sup.
