Question

A second cyclic form of the (7,4) Hamming code uses the generator polynomial g(x) = 1 + x2 + x3. a. If the message word is 1101, compute the codeword. Show all steps. b. Let the fourth-bit of your codeword in part 4(a) be in error when it is received. What is the syndrome? Show all steps in deriving the syndrome. Please do correct. I am unsure if the polynomial of 1101 is x^3 + x^2 + 1 or if it is x^3 + x + 1. In turn, I am unsure if that makes the answer 1101 000 or 11010010
