| 摘 要： | 分析了蓝牙跳频序列的汉明相关特性、序列平衡特性、组网特性和系统容量,指出某些蓝牙跳频序列在时钟同步时会出现严重的碰撞,并提出了相应的解决办法,其中一个较好的解决办法是同一区域任意2台蓝牙设备的地址A27-0在3个部分A27-19、A18-14,12,10,8,6,4,2,0和A13,11,9,7,5,3,1中都有不同位,且不同位分布尽可能分散,不同位数越多越好。

| Abstract: | Properties of Bluetooth frequency hopping sequences, including Hamming correlation property, property of balance, multiple-access property and capacity of FH communication system, are analyzed. Some of the bluetooth FH sequences will overlap seriously if they are synchronized in time, so solutions to this problem are presented. The best one among them is, in one district, that addresses A27-0 of any two Bluetooth devices should be different from each other in three parts: A27-19, A18-14, 12, 10, 8, 6, 4, 2, 0 and A13,11, 9, 7, 5, 3, 1, the more the different bits'' number of the Bluetooth addresses is, the better it is. The different bits should be distributed as scattered as possible. |
