【Abstract】 Linear complementary dual (LCD) codes and cyclic codes are two important types of error correction codes, which have important applications in communication systems, data storage, and cryptography. This article uses the structure of cyclic codes to construct quaternion LCD cyclic codes, analyzes their parameters, determines their dimensions, and then gives the lower bound of their minimum distance.
【Key words】 constacyclic codes; linear complementary dual (LCD) codes; generator polynomial
