Abstract
A decoding method of Reed-Solomon code produces an error position polynomial .sigma.(x) and an error evaluation polynomial .omega.(x) by a Euclidean algorithm, whereby a syndrome polynomial S(x) is obtained, the highest degrees of the syndrome polynomial S(x) and of an initial polynomial x.sup.2t, which is determined by the number t of symbols to be corrected, are multiplied, while the degree is incrementally reduced, thereby obtaining polynomials h(x) and g(x) that satisfy the relation:
