An explicit expression for Euclidean self-dual cyclic codes of length $2^k$ over Galois ring $\mathrm{GR}(4,m)$

Yuan Cao, Yonglin Cao, San ling +1

For any positive integers $m$ and $k$, existing literature only determines the number of all Euclidean self-dual cyclic codes of length $2^k$ over the Galois ring $\mathrm{GR}(4,m)$,…
