One Generator (1+μ)-Quasi Twisted Codes Over F^2+μF^2

摘要

This document gives the minimum generating sets of three types of one generator (1+μ)-quasi-twisted (QT) codes over F^2+μF^2, μ2=0. Moreover, it discusses the generating sets and the lower bounds on the minimum Lee distance of a special class of type one generator QT codes. Some good (optimal or suboptimal) linear codes over F^2 are obtained from these types of one generator (1+μ)-QT codes.
