| 摘 要： | 测试结果表明，蓝牙23跳系统的信道跳频序列并没有很好的汉明相关特性。从序列构造中的结构特征来看，汉明相关性恶化的主要原因，是码序列相邻分组中偶、奇码段都有恒定的段间隔(例如23跳为8)。针对这个原因，探讨性地给出一个方法，将恒定的段间隔修改为利用一个随机产生的固定段间隔表，测试发现，此措施可以显著地改善汉明相关性能。

| Abstract: | Faulty Hamming correlation of channel frequency hopping sequences in Bluetooth 23-hop system is proved experimentally. The analysis of constructive characteristics of building sequences shows that the main reason of faulty Hamming correlation is an invariable interval of the even and odd segments in adjacent blocks (example 8 in 23-hop). A pertinent method has been put forward, which adopts a fixed segment interval table that is generated randomly to replace original invariable interval and this method can remarkably improve the Hanming correlation. |
