甚高频ACARS通信系统物理层信号处理单元设计

摘要

According to research on the physical layer of civil aviation ACARS (ARINC Communication Ad-dressing and Reporting)communication system,the DSB-AM/MSK (Double-Sideband Amplitude Modulation/Minimum Shift Keying)modem based on the general signal processing platform is developed. By introduction of CSMA (Carrier Sense Multiple Access)busy detection and channel quality detection mechanism,and combin-ing actual engineering application,the stable and reliable inter-communication with international civil aviation radio is realized,which establishes a foundation for independent development of civil aviation ACARS digital communication system.%　　通过对民航ACARS数据链通信系统物理层的深入研究，采用通用信号处理开发平台，设计开发了DSB-AM/MSK调制解调器，引入CSMA忙闲检测及信道质量检测机制，结合实际工程应用，实现了与国际民航电台的可靠互通，为民航ACARS通信系统的自主工程研制奠定了基础。
