Abstract: The bilateral real time data transport for safety supervision system for train and ground has become a bottleneck in the development of safety supervision system for railway at present. It receives more and more attention from the society to set up an information channel for stationary object and mobile object. This article introduces the practice to apply this technology to mobile data access system for railway from the basic theory and technical features of software radio technology.
