摘要
随着近年来铁路运输的快速发展,对信号在轨道电路上传输和机车信号能正确显示的要求也越来越高．分析UM71移频信号的特点及其干扰信号,采用频谱分析、小波分析等先进技术,提出时域与频域互补的移频信号解调方案．
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.
