摘要：
Automatic Train Protection (ATP) System of Urban Railway Transit is very important for a train's safe run, where the effective transmission of train control information is the most significant. In the research of nationalization for ATP system capitalized by Ministry of Constructions and Ministry of Railways of China, Frequency Shift Keying (FSK) is adopted to modulate the train control information, for it needn't estimate phase of carrier wave. This paper introduces a kind of computer simulation method of FSK in details and solves some key techniques, such as how to make the FSK simulation as a Real-time system with continuous phase as well as dynamically changed codes and frequencies of FSK. F S K simulated by computer has been used in ATP simulation system and it has shown good effects.
