摘要 利用多项式剩余类环Z2m[x]/(xp-1)上的幂等元定义了一类Z2m环上的二次剩余码,该码具有良好的对称性质,并讨论了其相应扩展码的自对偶性质. A kind of quadratic residue codes is defined by idempotent generator over polynomial resi- due class ring Z2m [ x ] / (x^p - 1 ). These codes have good symmetry properties. The self-dual about the extended codes from these quadratic residue codes are also discussed.
