摘要：
Common method for balise uplink signal demodulation are coherent demodulation, non-coherent demodulation and zero-crossing detection. Based on the characteristics of balise uplink signal modulation method, this paper adopts the time-frequency analysis method of Adaptive Optimal Kernel (AOK) to demodulate the original balise uplink signal received by on-board equipment. According to the European FFFIS (Form Fit Function Specification) coding/decoding strate*, to decode the demodulated signal, the demodulation performance of the demodulation method is analyzed by the accuracy of the decoding results of a large number of demodulated data. The results showed that the time frequency analysis method of AOK can accurately demodulate the uplink signal in the transmission process, its bit error rate is almost zero and has a good demodulation effect.
