序列偶是近些年来应用于扩频通信理论研究的新的信号集,这种在通信收发双方采用不同序列作为一个地址码信号的方法大大扩充了系统容量。文中定义了一类新的序列偶形式——不等周期序列偶,研究了不等周期序列偶的相关性质,存在条件。同时文中提出了不等势集差集偶的区组设计概念,给出了与二元二值自相关不等周期序列偶间的等价关系,从而为二元二值自相关不等周期序列偶的数学构造提供了有力依据。
The sequence pair is a new signal set applied in the study of spread spectrum communication in recent years. This method of using different sequences as an address code signal in both the transceivers greatly expands the system capacity. In this paper, we define a new kind of sequence even form, unequal periodic sequence couple, and study the related properties and existence conditions of unequal periodic sequence couple. In the meantime, the concept of block design of unequal potential difference set pair is proposed. The equivalent relation between two groups of binary self-correlation unequal periodic sequences is given. The binary periodic autocorrelation unequal periodic sequence Even the mathematical structure provides a strong basis.
