摘要
研究给出了一类基于循环码的常重复合码的构造,并利用指数和计算其参数.与相关的常重复合码相比,该码具有更多的码字,且渐近性较好.
In this paper,a construction of constant composition codes as subcodes of cyclic codes is given,and the parameters are computed by exponential sums.Compared to several related constant composition codes,our construction has more codewords and better asymptotical properties.
