摘要: 获得了李距离下Zq , q∈Z,q≥4上完全码存在的一个必要条件, 并且证明了李距离下Z4上完全码不存在.另外还证明了与李距离相关的另一种距离下Z4k上完全码也不存在

关键词: 分拆, 李重量, 完全码

Abstract: This paper obtain a necessary condition for the existence of Lee weight perfect codes over Zq , q∈Z,q≥4 and show that the Lee weight perfect codes do not exist over Z4. This paper also show that perfect codes do not exist over Z4k with respect to a new distance, which is related to Lee metric.

Key words: Lee weight, perfect codes, partition
