Abstract
Disclosed herein is a CRC generator polynomial select method for selecting a generator polynomial to be used in CRC coding and code checking, the method may include a first process of finding largest minimum Hamming distances Max.dof codes generated from given polynomials; a second process of finding code lengths n for codes having the largest minimum Hamming distances Max.dand determining a range n(r, Max.d)≦n≦n(r, Max.d); a third process of searching all polynomials for specific polynomials generating codes having d=Max.din the determined range; and a fourth process of selecting final generator polynomials having a smallest non-zero coefficient count and a lowest code undetected-error probability from the specific polynomials.
