【摘要】 蓝牙技术是一种全球开放的无线通信标准,其目的是在各种便携式设备之间建立短距离,低功耗,低成本的无线连接,以实现设备间互用和互操作的性能。蓝牙系统工作在无需许可的ISM频段,是构建个人无线局域网(PWAN)的主导技术。本文的主要工作集中在对各种干扰环境中蓝牙底层协议的性能进行分析和计算机仿真。作者首先以蓝牙规范1.1版本为基础,详细介绍和分析了蓝牙底层协议桟(无线层和基带规范)的具体内容。在此基础上,作者采用Systemview软件提供的各种功能模块建立了蓝牙系统模型, 仿真了蓝牙系统在AWGN信道中的性能。然后,通过建立模型,本文在理论上详细分析了AWGN信道和Rician衰落信道中蓝牙同信道干扰,邻信道干扰以及同频段IEEE802.11b干扰对蓝牙BER性能,数据以及语音链路性能的影响,并针对各种情况分别进行了详细的计算机仿真,其结果对蓝牙网络的铺设具有一定的指导意义。最后,作者还探讨了利用ROK101 007蓝牙模块和免费协议栈CStack建立蓝牙点对点试验系统的方案。制作了电路板并编写了简单设备发现应用程序。

【Abstract】 BluetoothTM is a worldwide open standard of wireless communication, which is expected to establish common,short-range,low-power and low-cost wireless connection between myriad portable devices and ensure their interoperability. Bluetooth operates at license-freed ISM band and is generally regarded as the dominant technology to construct Personal Wireless Area Network(PWAN).Based on Bluetooth Specification Version 1.1, this thesis presents detailed introduction and analysis on low-layer protocols of Bluetooth protocol stack. Systemview is adopted to simulate Bluetooth system. More efforts are focused on analysis and computer simulation of the cochannel interference and IEEE802.11b interference’s impact on Bluetooth performance respectively in AWGN and Rician fading channel. Furthermore, the scheme of designing Bluetooth point-to-point experimental system with the ROK101 007 module and free Bluetooth protocol stack CStack is discussed. Results in this thesis provide valuable references for the deployment of Bluetooth networks.
