摘要 通过定义一种从环F2+uF2+u2F2到域F2上新的Gray映射,将环F2+uF2+u2F2上的线性(1+u+u2)—循环码等距映射成域F2的线性循环码;进一步又给出了在码长n=3(mod 4)时环F2+uF2+u2F2上的线性(1+u+u2)—循环码的Gray象的生成多项式,这对构造新的好码具有重要意义。 This paper defined a new Gray map between codes over F2+uF2+u2F2 and codes over F2. By means of this map, it shown that the Gray image of a linear (1+u+u2)-cyclic code over F2+uF2+u2F2 is a binary-distance-invariant linear cyclic code. Furthermore, if n=3(mod 4), obtained the generator polynomial of the Gray images of (1+u+u2)-cyclic codes. It is significant to construct new good codes.
