面向ZigBee无线传输的跳频扩频技术

ZigBee技术虽然使设备的快速联网更加方便快捷，但其网络的安全完全依赖于网络密钥并缺乏有效的安全配置选项，导致密钥在设备配对过程中极易泄漏，并因此对用户信息安全造成极大的威胁。本文给出一种基于跳频扩频技术的ZigBee传输方法，该方法通过传输过程中载频的不断跳变使得密钥信息无法被跟踪截获，增强了ZigBee网络安全性。基于该方法，本文建立了QPSK跳频扩频传输系统模型并进行了仿真验证。仿真结果表明，使用跳频扩频技术的QPSK无线传输系统具有良好的可靠性。

Frequency Hopping Spread Spectrum Based on ZigBee Wireless Transmission

Although ZigBee technology makes fast networking more convenient, its network security completely depends on the network keys and lacks effective security configuration options, which makes the leak of keys and the lack of user information security. Based on frequency hopping spread spectrum technology, a ZigBee transmission method is proposed, which makes it difficult to track and catch the information of keys and enhances the ZigBee network security. Based on the proposed method, the model of QPSK frequency hopping spread spectrum transmission system is established and verified by simulation. The simulation results show that the QPSK wireless transmission system with frequency hopping spread spectrum technology has a good reliability.
