| 摘 要： | 现阶段民航地空数据链系统是以ARINC-618协议为基础的,报文的编码形式不同于典型的MSK信号。利用现有的MSK技术实现民航地空数据链系统的研制开发,不仅可以缩短研制周期,同时也能够确保技术的成熟。通过分析ACARS信号和典型MSK信号编码方式的特点,建立了实现两种编码方式相互转换的映射关系,并从理论上证明了这种映射具有1—1对应关系,确保了两种编码格式转换的唯一性,为基于MSK的地空数据链通信调制解调提供保证。

| Abstract: | Civil Aviation Air-Ground Datalink system is based on the ARINC-618 protocol at the present stage, and the encoding form of its message is different from the typical MSK signal. But the utilization of the existing MSK when researching and developing the Air-Ground Datalink system, can not only shorten the research cycle but also ensure the technology mature. This paper establishes a mapping relation of interconversion between ACARS signal and typical MSK signal in accordance with their features, and proves the 1-1 correspondence of this mapping relation in theory, which ensures the uniqueness of the conversion between these two encoding forms and guarantees the modulation and demodulation for the Air- Ground Datalink communications based on MSK. |
