Regarding frequency band allocation problem faced with the channel multiplexing when combination of train control network and information network, according to the original definition of random process power spectrum, a mathematical model of MVB code is established and a MVB frame head frequency spectrum function is deduced, and different MVB frames power spectrum are calculated and simulated. Then using a design of band-limited filter which can ensure normal safe operation of the baseband transmission system, at the same time which can reduces interference of the baseband signal on the high frequency carrier signal, thus optimizing the bandwidth of the MVB baseband transmission system. Finally, verify the effectiveness of the design through simulation analysis and experimental testing.
