摘要：
In this correspondence, we study cyclic codes of length n = 2(e) over the ring R-4 = Z(4) [x]/(x(n) - 1). In particular, we derive a closed-form expression for the number of these codes for a given length n. We also study the rank of these codes and derive an expression for that. Furthermore, we give an example in which we study all cyclic codes of length 8. We also study all self-dual codes of length 8 and 16 and classify them according to their type.
