几乎最佳自相关二元序列偶的谱特性

Spectrum Characters for Almost Perfect Autocorrelation Binary Sequences Pairs

首先提出了几乎最佳自相关二元序列偶的定义。研究了几乎最佳自相关二元序列偶的Fourier谱特性,应用这些谱特性给出了几乎最佳自相关二元序列偶的重量分布情况,推导出了几乎最佳自相关二元序列偶中两个序列之间的汉明距离与每个序列的奇位和、偶位和的关系。

The concept of almost perfect autocorrelation binary sequence pairs is given. The Fourier spectrum characters of almost perfect autocorrelation binary sequence pairs are studied. The distributions of the weights of almost perfect autocorrelation binary sequence pairs are given by using this spectrum characters. The relation of hamming distance of two sequences and the distributions of sequences' elements is deduced.
