| Abstract: |
| This papaer introduces the civil aviation Very High Frequency（VHF） Aircraft Communication Addressing and Reporting System（ACARS） communication system and the air-ground communication management using the ACARSIP handling mechanism based on the civil aviation VHF ACARS communication system. The ACARS communication messages handling mechanism based on DSP and FPGA is used in the civil aviation VHF ACARS communication system,and the design and implementation of up-link signal processing, down-link signal processing, Carry Sense Multiple Access（CSMA） mechanism, channel quality detecting, subnet data statistics and audit pattern is described. Finally, the ACARS communication messages handling mechanism is analyzed and summarized, and its application future is pointed out. This scheme has been applied in china′s first civil aviation ACARS data-communication system, and a stable communication quality of 100% correct rate of receiving is achived as communicating with the international civil aviation radio. |
