摘要

研究了长度为2n的偶移正交序列的性质，该序列的相外非周期自相关函数在任意偶移处取零。证明了逻辑函数产生的所有n为奇数的e序列的一半都是平衡序列，其中元素1和-1都是一半，并且不存在偶数n的平衡e序列。此外，还证明了非周期自相关函数在奇移处具有低值。

Properties of Even-Shift Orthogonal Sequences

This paper investigates properties of the even-shift orthogonal sequence of length 2n, whose out-of-phase aperiodic auto-correlation function takes zero at any even shift. It is shown that the halves of all E-sequences with odd n produced by logic functions are balanced sequences, whose elements 1 and -1 appear half, and there is not any balanced e-sequence for even n. Furthermore it is also shown that the aperiodic auto-correlation function possesses low values at odd shifts.
