Abstract
This paper is devoted to the construction of two-Lee weight codes over with type based on a distance-preserving Gray map from to . The necessary conditions for a code over to have only two different nonzero weights are given. The existence of two-Lee weight projective codes is also presented. Finally, some examples are also presented to illustrate the algebraic structure of two-Lee weight codes over .
