研究了一类链环上型为8k的线性码的支重量分布与Hamming重量分布的关系,利用MacWilliams恒等式建立了该链环上线性码的支重量分布与其对偶码的支重量分布之间的关系.
The relation between the support weight distribution of a linear code of type 8k and the Hamming weight distribution was established,and the relation between the support weight distribution of the linear code and its dual was derived by MacWilliams-identity over the ring.
