Abstract: |
In this paper, we study the self-dual codes over the ring R=F2+uF2+vF2. According to the Gray map from Rn to F23n and the fact that the Gray image of self-dual code C over the ring R is the self-dual code over F2, we obtain the conclusion that there exists self-dual codes with any even length over R. Finally, we propose two structural methods of self-dual codes over the ring R. |
