轨道电路移频信号参数检测算法研究
代码说明：
说明： 轨道电路移频信号是用来控制列车的行驶状态．对其参数的检测需要达到较高的频率分辨率，分析了国产18信息和ZPW一2000型两种制式移频轨道电路的移频信号的频谱特点，提出r采用CZT线性调频z变换和时域测量相结合的方法检测移频信号的参数。在MATLAB环境下编写CZT算法进行仿真，仿真结果表明。(Track circuit frequency-shift signal is used to control the train operation, and the parameter detection should achieve high frequency resolution requirements. According to the sampling theorem knowledge, we know that it needs longer sampling time. In order to attain high frequency resolution in a relatively short period of sampling time, the paper analyzed the spectrum characteristics of the frequency-shift signaling in the two formats track circuit. At last, we compiled CZT algorithm in the MATLAB environment.)
