On the Weight Distribution of Some Justesen Codes

摘要

Justesen first constructed asymptotically good concatenated codes such that the outer code is Reed-Solomon (RS) code and the inner code is Wozencraft's ensemble of randomly shifted codes. Kolev gave the weight distributions of Justesen codes in some cases. In this paper, we give the weight distributions of Justesen codes obtained by using some other RS codes as the outer code.
