On the generalized Hamming weight enumerators and coset weight distributions of even isodual codes

摘要

We address the problem of computing the generalized Hamming weight enumerators (GHWE) of even isodual codes. We also demonstrate that the GHWE and coset weight enumerators (CWE) of even isodual codes are closely connected and that in certain cases one set of these enumerators can provide sufficient information for determining the other.
