摘要
结合正交数字上/下变频技术,频率编码方式及其合成技术,提出了一种数字编码轨道电路发送方案,并采用DSP实现了这种轨道电路发送器,实验验证表明本方案具有性能稳定、可靠等优点。
It was presented a transmission method of the digital coding track circuit based on the quadrature digital up converter, frequency coding mode and synthesis technology. The transmitter for the digital coding track circuit was implemented with DSP. The experimental results showed that the Transmission System was stable and reliable.
