Extending self-orthogonal codes
Extending self-orthogonal codes
In this short note we give an exact count for the number of self-dual codes over a finite field $F_q$ of oddcharacteristic containing a given self-orthogonal code. This generalizes an analogous result of MacWilliams, Sloane, andThompson over the field $F_2$ to arbitrary odd finite fields $F_q$.
