摘要

常用的信道上行信号解调方法有相干解调、非相干解调和过零检测。本文根据balise上行信号调制方法的特点，采用自适应最优核(AOK)时频分析方法对星载设备接收到的原始balise上行信号进行解调。根据欧洲FFFIS (Form Fit Function Specification)编码/解码策略对解调信号进行解码，通过对大量解调数据的解码结果的准确性来分析解调方法的解调性能。结果表明，AOK时频分析方法能准确解调传输过程中的上行信号，误码率几乎为零，具有良好的解调效果。

Balise uplink-signal demodulation method based on adaptive optimal kernel time — Frequency analysis

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 strategy 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.
