Additive complementary dual codes over $\mathbb{F}_{q^2}$

Shi et al. [Additive complementary dual codes over F4. Designs, Codes and Cryptography, 2022.] studied additive codes over the finite field F4 with respect to trace Hermitian and trace Euclidean inner products. In this article, we define additive codes of length n over finite field Fq2 as additive subgroups of Fn q2 where q is a prime power. We associate an additive code with a matrix called a generator matrix. We characterize trace Euclidean ACD and trace Hermitian ACD codes in terms of generator matrices over the finite field Fq2 . Also, we construct these codes over Fq2 from linear LCD codes over Fq.
