基于TDD模式的无线语音及数据传输系统研究

Design and Research of Wireless Voice and Data transmit system Base on TDD mode

设计了一种针对短距离通信的、全双工、低功率无线语音及数据传输系统,并对系统的硬件实现和软件设计进行了详细阐述,特别讨论了该系统通信协议的设计和通信过程的实现。系统不但能实现无失真语音传输,而且可传送一些必要数据信息,能使用液晶显示屏显示英文和汉字短信,且具有数据传输误码率低的特点。

A wireless Full-duplex low power voice and data transmit system for short-distance communication is introduced in terms of the design of its hardware and software, especially the whole system＇s protocol and the process of the communication are represented in detail. The system can not only realize voice transmission, but the essential data could be transmitted,and there is no obvious voice distortion and low bit error rate during transmission. In addition,the short message could be displayed on liquid crystal display（LCD）,including the English words 、Chinese characters.
