Webp(x), and then multiply with a code generator polynomial g(x) •We construct code generator polynomial g(x) with n –k factors, each root being a consecutive element in the Galois field •α is a primitive element, an alternative way of specifying elements in a field as successive powers 0, α0, α1, α2 … αN where N = 2q - 1 Webof zero. Fields satisfy a cancellation law: ac = ad implies c = d, and the following argument shows that a fields cannot have divisors of zero. Suppose ab = 0 for a 6= 0. Since a0 = 0 we can rewrite ab = 0 as ab = a0 and thus by the cancellation law b = 0. This shows that in any field if ab = 0, then either a = 0 or b = 0. Therefore, high voicemail
