I want to how to get a^12
Syndrome Now if the data read has 3 errors, such as r(x) = (100100100101011), the syndrome can be found from the following equations. Due to t= 3, we have 2t = 6 syndrome elements needed in order to find t errors.
S(x) = r(x) mod f(x) sz(x) = r(x) mod f(x) = r(x) mod f(x) Sz(x) = r(x) mod f(x) S4(x) = r(x) mod f(x) = r(x) mod f(x) S5(x) = r(x) mod f5(x) 56(x) = r(x) mod f.(x) = r(x) mod f3(x)
In selecting the minimal polynomials, we take advantage of the property of field elements whereby several powers of the generating element have the same minimal polynomial. When f(x) is a polynomial over GF(2), a is an element of GF(2"). Then we form a system of equations in a as follows: S(a) = r(a) mod f(a) = a + ( + a + 1 = a12 szl(?) = r(a) mod f((?) = r(a) mod f,(a?) = q* + a = sz(a) = r(a) mod f(a) = a + (n + a2 + 1 92 s.(a*) = r(a) mod f.(a) = r(a) mod f,(a") = a?? + a + q* + 1 € C3 Ss(as) = r(a) mod f(a) = 5 so(aa) = r(a) mod fo(aº) = r(a) mod f3(aº) = a18 + a?? + d + 1 aº
