基于Bluetooth技术的无线通信系统研究
|
摘要
蓝牙技术是一种新兴的短距离无线通信技术，其目标是以无线连接取代有线连接，将固定和移动信息设备组成个人局域网，实现设备之间低成本的无线互连通信。本文对蓝牙技术进行了研究，首先介绍了蓝牙技术的发展历程及特点，然后论述了蓝牙基带协议、链路管理器协议、逻辑链路适配协议等协议，并就基于蓝牙技术的无线耳麦的协议栈及其实现进行了探讨。在此基础上设计了无线耳麦的实现方案，该方案以TI的新型超低功耗16位单片机MSP430F1121、无线收发芯片TRF6900和语音AD／DA芯片TLV320AC36作为硬件平台，采用针对MSP430系列单片机的汇编语言编写了基带处理程序，用以实现体现蓝牙技术的无线耳麦，最后对所做的工作进行了总结。
As a new kind of technology for short range wireless communication, Bluetooth aims to replace the cables between the information equipments with radio wave and establish a personal area network for them to communicate with each other. This paper is concentrated on the study of Bluetooth. First, the history and features of Bluetooth are introduced. Then the protocols of Bluetooth are discussed with emphasis on baseband protocol, link manager protocol, logical link control and adaptation protocol. The protocol stack and realization of wireless earmic based on Bluetooth are also explained. Based on these, the scheme of wireless earmic is presented. In this scheme, MSP430F1121, TRF6900 and TLV320AC36 are chosen as the hardwares for this system. The assemble language for MSP430 is adopted as programming language to develop baseband software. Finally wireless voice transmission in short distance is implemented.
