最佳三进序列偶的谱特性

Spectrum characters for the perfect ternary sequence pairs

首先给出最佳三进序列偶的定义,提出了重量距离与非重量距离的概念,研究了最佳三进序列偶的Fourier谱特性,应用这些谱特性给出了最佳三进序列偶的重量分布情况,并推导了最佳三进序列偶中两个序列的重量距离与每个序列的奇位和、偶位和的关系。

The definition of the perfect ternary sequence pairs is given. According to the propertity of the perfect ternary sequence pairs, the concepts of the weight distance and the non-weight distance are provided, compared with the hamming distance of the binary sequence pairs. The Fourier spectrum charaters Of the perfect ternary sequence pairs are studied. The distributions of the perfect ternary sequence pairs are given by using this spectrum characters. The relation of weight distance of two sequences and the distributions of sequences＇ elements is deduced.
