Y.S.Han Decoding BCH/RS Codes 9 error-locator polynomial is a hard problem and it will be mentioned later. The key equation becomes A()(1+S(2))=2(2)mod 224+1 (4) if we define the infinite degree syndrome equation as (5) j=1 School of Electrical Engineering Intelligentization,Dongguan University of Technology Y. S. Han Decoding BCH/RS Codes 9 error-locator polynomial is a hard problem and it will be mentioned later. • The key equation becomes Λ(x)(1 + S(x)) ≡ Ω(x) mod x 2t+1 (4) if we define the infinite degree syndrome equation as S(x) = ∑ ∞ j=1 Sj x j .
