| Abstract: | With the rapid development of railway transit, the requirements for the efficient transportation and the accurate signal analysis turn out to be more important. The different types of demodulation were introduced to guarantee the efficiency of the signal, and the efficient demodulation scheme was presented according to the requirement of the transportation and characteristics of the railway circuit, including many advanced technologies such as spectrum analysis and wavelet transform, to improve the security and disturbance greafly. |
