We firstly redefine the Chrestenson linear spectrum of logical functions over Finite Fields, which was ever offered in [1]. The linear spectrum proposed in this paper, as well as Chrestenson cyclic spectrum, is a mapping from Finite Fields into Complex Fields, so it is reasonable to study the relation between Chrestenson linear spectrum and Chrestenson cyclic spectrum. Finally, we show that any logical functions over finite fields can be deduced by a group of Chrestenson linear spectrum. |
