Covering Radius of Codes over Ring F_2+vF_2
Huang De-we · College Mathematics · 2015
Through the study of the structure of codes over ring F2 +vF2,two binary codes was defined.By means of the Gray map,one conclusion on the covering radius of codes over ring F2+vF2for the Lee distance was obtained.We study the covering radius of dual codes over ring F2 +vF2.Several upper and lower bounds on the covering radius were given.
