We extend Ravagnani's MacWilliams duality theory to the settings of rank metric codes over finite chain rings, relating the sequences of $q$-binomial moments of a rank metric code over this class of rings with those of its dual.
翻译:我们将Ravagnani的MacWilliams对偶理论推广到有限链环上秩度量码的情形,建立了该类环上秩度量码的$q$-二项式矩序列与其对偶码相应序列之间的对应关系。
