运用数传模块实现无线语音通信的方案设计

Application Of Wireless Data Transmission Module InScheme Design For Wireless Voice Communication

介绍了无线数传模块的工作原理及通信特点,结合实际无线语音保密通信系统,重点分析了数传模块应用中的几个难点,包括半双工通信协议、通信中的同步方法、数据的乒乓存储方式等。其方法对于无线数传模块应用设计具有普遍意义。

The operation principle and the communicating characters of wireless module are briefly introduced. A practical wireless secure system based on DSP for voice communication shows the difficulties in the application of the module in detail, which involves the half--duplex protocol, means to synchronize and storage of the data, etc. The method can he universally used on the design of wireless module application.
