摘要
研究了F4上维数为4的最优(或拟最优)自正交码的码长与极小距离之间的关系,用组合方法构造出任意码长的最优(或拟最优)自正交码的生成矩阵,确定了其中达到Griesmer界的码。
The relations between length and minimum distance of 4 dimensions optimal or near optimal quaternary self- orthogonal codes are investigated,the generator matrices of such random optimal or near optimal self-orthogonal codes are constructed by combinatorial method.Especially,the optimal self-orthogonal codes that achieve the Griesmer bound are determined.
