Self-Dual Codes over F3 and Negacirculant Conference Matrices
K. T. Arasu, Yu Chen, Thomas Aaron Gulliver, Weilai Song · 2006
Previously, self-dual codes ternary have been constructed from conference matrices. In this paper, we present codes constructed from negacirculant conference matrices. A necessary condition for these codes to be self-dual is given, and examples are given for lengths up to 108. The equivalence with the Pless symmetry codes is established
