摘要:
We give a 1-level squaring construction for binary repeated-root cyclic codes of length n = 2(a)b, a greater than or equal to 1, b odd. This allows us to obtain the weight distributions of all cyclic binary self-dual codes of lengths up to 110, which are not accessible by direct computation. We also use the shadow construction, as a particular method for Type I self-dual codes.
