摘要
目的研究F4上维数为3的最优(或拟最优)自正交码的码长与极小距离之间的关系。方法组合方法。结果构造出码长n≥21的3维最优(或拟最优)自正交码的生成矩阵,确定出了其中达到Griesmer界的码。结论给出了3维的最优自正交码码长与距离的规律。
Aim The relations between length and minimum distance of 3 dimension optimal or near optimal quaternary self-orthogonal codes are investigated. Methods Combinatorial method is used to construct 3 dimension optimal or near optimal quaternary self-orthogonal codes for length. Results The generator matrices of such optimal or near optimal self-orthogonal codes are constructed, and the optimal self-orthogonal codes that achieve the Griesmer bound are determined. Conclusion The characterization of optimal self-orthogonal codes of dimension 3 is given.
