摘要

This paper presents design of T-Direct codes over GF(2-(N)) with increased users. The class of T-Direct codes are an extension to the class of linear codes with complementary duals (LCD codes) and can be effectively used over a multiple access channel environment. In this paper, a construction procedure that constructs an n(3)-Direct code from an n-Direct code is described. An n(n)-Direct codes are also constructed. Further, a recursive construction procedure is presented that constructs n(3m) - Direct codes for m = 0. Finally, T-T -Direct codes with constituent codes having variable code rates are obtained. The advantage of these constructions is that it increases the number of constituent codes (users) of an existing T-Direct code, thereby supporting more users in a multi-user environment.
