在文献[1 0 ] 中 ,由旧码C1 、C2 构造了一类新码C1 C2 ———笛卡尔积码。本文根据文献[1 ]中提出的广义Hamming重量的定义 ,分析了笛卡尔积码与旧码C1 、C2 的广义Hamming重量的关系 ,给出了几个有意义的结果 In [10], a new class of C1 C2-Cartesian products is constructed from the old codes C1 and C2. Based on the definition of generalized Hamming weight proposed in [1], this paper analyzes the relationship between Cartesian codes and the generalized Hamming weights of old codes C1 and C2, and gives some meaningful results
