摘要 | The nonlinearity of the Z(2)-Kerdock code Km+1, where m is an odd integer greater than or equal to 3, is not at all obvious. By regarding Km+1 as the binary image of the Z(4)-Kerdock code K(m) under the Gray map([1]), a simple proof can be achieved (cf. Theorems 8.7 and 8.9 of [2]). Similarly, the formal duality of the Z(2)-Kerdock code Km+1 and the Z(2)-Preparata code Pm+1 is even more not at all obvious. A simple proof is given in the present note, by regarding Km+1 as the binary image of K (m) and using the duality of k(m) and the Z(4)-Preparata code P(m) established in [1]. |
