摘要 基于环F_p+vF_p(v^2=v)上线性码的一种直和分解,利用环F_p+vF_p上的线性码的Torsion码,把环F_p+vF_p上的线性码的极小支座谱的确定归结于有限域上的情形;进一步探讨了环F_p+vF_p上的线性码的校验矩阵,利用该校验矩阵确定了环F_p+vF_p上的线性码的对偶码的极小支座谱;最后利用环上的线性码的极小支座谱,探讨了环F_p+vF_p上线性码的最小Hamming距离,并且给出了一个环F_p+vF_p上最小Hamming距离为d的线性码的构造方法,这里p是任一个素数,d是一个正整数. Based on the direct sum decomposition of linear codes over Fp + vFp ( V2 = V ), the minimum support hierarchy of linear codes over Fp + vFp and their dual codes are studied by means of the Torsion codes and parity check matrice of these linear codes. With these results the Hamming distance of linear codes over Fp + vFp are determined in terms of that of linear codes over the fmite field Fpand an explicit construction for linear codes over Fp + vFp are given with the Hamming distance d, wherepis a prime and dis a positive integer.
