Constant composition codes as subcodes of linear codes

In this paper, on one hand, by a kind of defining set we construct a class of optimal linear codes, whose weight distribution is determined. Furthermore, we propose a class of constant composition codes (CCCs) from optimal linear codes. some of these CCCs are optimal depending on LFVC bound. On the other hand, a class of constant composition codes are constructed from known linear codes and the parameters of these CCCs are completely determined.
