On Orthogonal Circulant MDS Matrices

In 2019, Cauchois and Loidreau gave a necessary and sufficient condition for circulant maximum distance separable (MDS) matrices using q-polynomial rings. This work proves the non-existence of certain orthogonal circulant MDS matrices. The study also provides a necessary and sufficient condition for orthogonal θ-circulant matrices using q-polynomial rings. The orthogonal circulant MDS matrices over Galois rings are also discussed.
