摘要 首先将广义准循环码的概念推广到环Z2k1+上,然后仿照Fq上广义准循环码的生成元的形式,给出了环Z2k1+上的1-生成元广义准循环码C的生成元的具体形式,最后通过给出C为Z2k1+自由模的充分条件,得出C为自由模时码C的维数及最小距离. The paper generalizes the GQC codes to the ring Z2k+1,then imitates the form of generator from GQC of Fq to give the specific form of Z2k+1.Lastly,with C being the sufficient condition of Z2k+1 free module,the dimensions and the minimum distances are obtained when C is free module.
