最近，蓝牙技术有望成为发展最快的技术之一，它使消费电子设备能够通过短距离链路进行连接和通信。蓝牙无线电以1600跳/秒的速度在2.4 GHz频带上跳频工作。针对蓝牙多跳网络，提出了一种基于3DES迭代分组密码的跳频序列。本设计提供了一类族数大、独立性好、在ISM频宽上分布均匀的蓝牙跳码，支持微网间的单位跳码。在理论上推导了同步多跳蓝牙网络的分组误差和吞吐量性能的基础上，许多数值结果表明，所提出的序列在piconet的多址访问方面具有与随机模式相同的性能。在FPGA中有效地实现了所提出序列的生成器原型，并且非常适合在蓝牙无线电中使用(1)。
Recently, the Bluetooth technology is expected to be of the fastest growing which enable consumer electronic devices to connect and communicate via short-range links. The Bluetooth radio operates on frequency hopping over the 2.4 GHz band at 1600 hops/s. In this paper, a novel family of frequency hopping sequences based on 3DES iterated block cipher is proposed for Bluetooth multi-hop networks. The design offers a class of Bluetooth hopping codes with large family size, good independence and a uniform spread over the ISM frequency bandwidth, which support jumping of unit between piconets. With the performance of packet error and throughput for synchronized multi-hop Bluetooth network being derived in theory, many numerical results shown that the proposed sequences perform as well as random patterns in terms of multiple access of piconets. Efficiently implemented in FPGA, the generator prototype of the proposed sequence has been realized and is well suited for employment in the Bluelooth radios(1).
