Abstract:
In this letter, we discuss the construction of all constacyclic codes over R = ℤ4 [v]/(v 2 - v). Some significant properties of linear codes over R have been explored. The selfdual constacyclic codes for odd length over R are determined. Several examples of (1 + 2v)constacyclic codes and (3 + 2v) constacyclic codes over R, whose ℤ4 -images are new ℤ 4 -linear codes with better parameters, are provided
