Abstract: Based on the structure of the cyclic codes over the ring F2+uF2,an accurate formula about the minimum distance distribution of the cyclic codes over the ring F2+uF2 with length 2s is given.

Key words: linear cyclic code, Hamming distance, Lee distance

摘要: 研究了环F2+uF2上线性循环码的极小距离分布。首先给出了环F2+uF2上线性循环码的结构,利用该结构给出了长度为2s线性循环码的极小距离分布的精确表示。
