摘要: 子空间码因其在网络编码中具有广泛应用,已成为编码理论的主要研究对象之一。在子空间码的多重构 造方法中,最优Ferrers 图秩距离码的构造至关重要。本文利用极大秩距离(MRD,maximum rank distance) 码的子码构造了3类最优Ferrers图秩距离码,并通过实例说明所构造的码是新成果。

Abstract: Subspace codes have become one of the major research objects in coding theory due to their extensive applica鄄 tions in network coding. The construction of optimal Ferrers diagram rank-metric codes is crucial for the diversi鄄 fied construction methods of subspace codes. In this paper, three classes of optimal Ferrers diagram rank-metric codes are constructed using the subcodes of maximum rank distance (MRD) codes. Concrete examples further verify that the constructed codes are new constructions.

Key words: maximum rank distance (MRD) codes, Gabidulin codes, Ferrers diagrams, Ferrers diagram rank-metric codes
