对于给定的奇素数p,定义了F2上码长为p的8种四次剩余码,研究了这8种四次剩余码之间的关系,给出了四次剩余码的码字重量、极小汉明距离一些好的性质,给出了四次剩余码的幂等生成元和对偶码的生成多项式.
For a given odd prime p,eight biquadratic residue codes over F_2 were defined.The relation between the eight codes was researched.Some good properties of weight and the minimum Hamming distance of the codes were given.Finally,the generating polynomials of their dual codes and the idempotent generator of biquadratic residue codes were calculated.
