    Abstract
  • The characteristic of balise uplink-signal was analyzed. An adaptive demodulation method for balise uplink-signal was introduced. The frequency of uplink-signal was tracked by using adaptive least mean square (LMS) algorithm. The signal was demodulated according to the calculated tracking residual. The demodulation performance was verified according to the Eurobalise test specification and then compared with zero-crossing detection method and noncoherent demodulation method. Simulation result shows that adaptive demodulation method can meet the demodulation performance requirements when there exists extreme migration of uplinksignal. When the signal to noise ratio (SNR) is 7 dB, the error rate of adaptive demodulation method is almost 0, while the error rates of the zero-crossing detection method and the noncoherent demodulation method are 0.163 and 0.001 respectively. The adaptive demodulation method is simple to utilize and has strong anti-interference ability. It provides a foundation for the reliable application of balise in comparative harsh electromagnetic environment.
