We study the relationship between cyclic codes over F3 + vF3 and ternary cyclic codes, and prove that cyclic codes over the ring are generated by a polynomial over F3 + vF3. Then, using similar method, we obtain the generator polynomial of v-constacyclic codes %K 循环码 常循环码 Gray映射 生成多项式< %K br> %K cyclic codes constacyclic codes Gray map generator polynomial %U http://sxzz.whu.edu.cn/sxzz/ch/reader/view_abstract.aspx?file_no=20150512&flag=1
