On the Subcode-Support-Weight Distributions of Some Classes of Optimal Codes
Yu Luo, Zihui Liu · IEEE Transactions on Information Theory · 2022
Based on the concept of the value assignment and the enumeration techniques in the projective space, we determine the subcode-support-weight distributions for several classes of linear optimal codes which were constructed recently by using the so-called down-sets. Particularly, the generalized Hamming weights of these classes of optimal codes can be determined from their subcode-support-weight distributions. By using the value assignment, we also determine the trellis complexity of each class of optimal codes.
