| 摘 要： | 提出了一种利用平方剩余差集(4t-1,2t-1,t-1) DS和差集偶(N,p,q,e,λ) DS P构造二元零相关区(ZCZ)序列偶集的方法. 由平方剩余差集获得其二元特征序列，并由差集 偶获得其特征二元序列偶，将二者进行交织构造生成一类新的二元ZCZ序列偶集. 该方法解 决了现有二元ZCZ序列偶集构造中含有少量非二元元素的问题，通过选择适当的差集偶可使构造的二元ZCZ序列偶集在失配滤波检测中获 得较高的能量效率，从而提高了通信性能. |
| 关 键 词： | 平方剩余差集 差集偶 二元零相关区序列偶 能量效率 |

| Abstract: | A new class of binary sequence pair sets with zero correlation zone (ZCZ) is constructed by interleaving characteristic sequences from quadratic difference set (4t-1,2t-1,t-1) DS and sequence pairs from difference set pair (N,p,q,e,λ) DSP. This method solves the problem that some non binary elements exist in the binary sequence pair sets with ZCZ constructed so far. Meanwhile, by selecting the appropriate difference set pairs, the proposed binary sequence pair sets with ZCZ can achieve satisfactory energy efficiency in mismatched filtering. |
| Keywords: | quadratic difference set difference set pair binary sequence pair with zero correlation zone energy efficiency |
