提出了提高移动信道可靠性的信道编码方法和适用于中国铁路（准高速以下）的专用移动数据通信协议，介绍了两种典型的移动数据通信模型和一种预测移动数据传输性能指标的方法。提供了从移动数据通信试验系统中所得出的有关结果。着重介绍了信道编码方法和数据通信协议在沈丹线数话兼容无线列调系统中的应用。
A channel coding method for improving the reliability of mobile channel and a dedicated mobile data communication protocol suitable for China’s railway (under quasi-high speed) are proposed. Two typical models for mobile data communication and one method for predicting the performance of mobile data transmission are introduced. The results obtained from the mobile data communications test system are provided. The application of channel coding method and data communication protocol in the wireless data transfer system of Shenyangtan digital line-up is emphatically introduced.
