中文摘要：

介绍了一种基于TDD方式的高语音清晰度、高移动性的无中心数字无线语音传输系统,为了实现高性能,选择CC1101射频收发作为主芯片,以MSP430F149（MCU）为控制芯片,可以体现控制芯片的低功耗特点,以及选择AMBE-1000（国产）语音编解码芯片进行语音处理,则可以较小的语音数据量来实现清晰语音,从而有效的节省传输带宽,其他芯片则是良好的辅助。在通信协议的设计中引入了非对称的帧格式设计,从而与射频模块匹配,在编程架构设计上运用了层次化与模块化相结合的编程方法加快软件的开发速度。文中详细介绍了系统的设计方案及各芯片选型,MCU软件设计调试,以及硬件设计与调试要点。

英文摘要：

This paper describes the high-definition,high-mobility and no-center digital wireless voice transmission system based on TDD mode.In order to achieve high performance,with RF main chip CC1101 as transceiver and Microcontroller（MCU） MSP430F149 as the control,the characteristics of low power could be reflected,and with AMBE-1000（for voice processing）,the intelligible voice could be achieved with small-quantity speech data,thus effectively saving the transmission bandwidth,while the other chips are the good assistants.The non-symmetrical frame format is introduced into the design of communication protocol,thus to match the RF modules.The combination of hierarchical and modularization programming could accelerate the pace of software development.This paper discusses in detail the system design and chip selection,software design and debug for MCU,and hardware design and debug.
