Abstract

In this paper, we construct several infinite families of qq-ary constacyclic codes over a finite field Fq\mathbb{F}_q with length nn, dimension around n/2n/2, and minimum distance at least cn/logqncn/\log_q n for some positive constant cc. They contain many constacyclic codes with optimal, or almost-optimal, or best-known parameters. We also consider constacyclic codes of various lengths.
