Johnson方案中的完美单纠错码

Perfect single error-correcting codes in the Johnson Scheme

Daniel M. Gordon

摘要:

Delsarte在1973年证明了Johnson方案中不存在非平凡的完美码。Etzion和Schwartz最近证明了对于大k,完美码必须是k-正则的,并利用这一点证明了当n <= 50000时,不存在纠正J(n,w)中单个错误的完美码。本文证明了当n ≤ 2^250时,不存在完美的单纠错码.

英文摘要:

Delsarte conjectured in 1973 that there are no nontrivial pefect codes in the Johnson scheme. Etzion and Schwartz recently showed that perfect codes must be k-regular for large k, and used this to show that there are no perfect codes correcting single errors in J(n,w) for n <= 50000. In this paper we show that there are no perfect single error-correcting codes for n <= 2^250.
