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
