Arailway communication signal acquisition model and simulation analysis are researched, through the extraction of High-speed Rail remote simplex communication signal optimal impulse control, and signal processing, the communica?tion transmission of high-speed railway train control system of CTCS-3 train ground is realized. Based on the High-speed Rail remote simplex control best communication signal pulse extraction algorithm of single frequency envelope of instanta?neous value statistics, High-speed Rail CTCS-3 train control system of train ground communication model, signal extrac?tion is obtained. On the characteristics of interference of multipath channel, the train control center receives the signal of the impulse response of linear filtering, calculation of the receiving end of the directivity gain, and remote control High-speed Rail simplex optimal impact communication signal generated by the pulse response extraction is realized. The simula?tion results show that, the algorithm can simulate the channel reverberation of ground column CTCS-3 system effectively, and the optimum extracting impulse response pulse is obtained. It improves the communication transmission quality of CTCS-3 system.
