摘要
跳频扩频是主要的扩频编码技术之一,跳频序列在跳频码分多址系统中的作用至关重要。分圆理论由于具有良好的特性,在组合设计、良好的二元随机序列设计中得到了广泛应用。基于分圆理论,构造了一类关于Peng-Fan界最优的跳频序列集,节省了一个频隙,丰富了跳频序列集的构造方法。结果表明,该构造方法简单易行,对跳频通信系统性能的提高具有一定的指导意义。
Frequency-hopping （FH） spread spectrum is one of the main spread spectrum coding technologies.Furthermore, frequency-hopping sequences （FHS） play important roles in FH code division multiple access systems. Due to its good characteristics, the cyclotomy has been widely used in combinatorial designs and good designs of binary random sequences. Based on eyclotomy, a class of FHS set with Peng-Fan bounds is constructed, which can save a frequency gap and enrich the construction methods of FHS sets. The results show that this method is simple and easy to be implemented, and it has a certain guiding significance for improving the performance of FH communication system.
