数字化通用式机车信号在极频区段的使用

Use of Polar Frequency of Digital Cab Signal

数字化通用式机车信号采用数字信号处理技术， 在原有硬件不变的情况下增添了极频制式的接收功能， 提高了机车信号的通用性。

This paper introduces how to add the polar frequency system to the universal cab signaling under the condition that all the hardware remains unchanged,and how to use this kind of function to raise the common use of cab signal.
