Discrete Math in Coding Theory

This Special Issue comprises eleven articles on the algebraic, combinatorial, and geometric aspects of Coding Theory. The topics range from applied (error detection probability, sonar sequences, optical codes, codes for constrained systems, and storage codes) and algebraic (AG codes for the Hermitian curve, LCD codes, and codes over the Eisenstein integers) aspects to combinatorial (permutation arrays, two-weight codes, and Boolean functions) ones.
