Abstract: |
According to research on the physical layer of civil aviation ACARS(ARINC
Communication Addressing and Reporting) communication system,
the DSB-AM/MSK(Double-Sideband Amplitude Modulation/Minimum Shift Keying) m
odem based on the general signal processing platform is developed.By introductio
n of CSMA(Carrier Sense Multiple Access) busy detection and channel quality detection mecha
nism,and combining actual engineering application,the stable and reliab
le inter-communication with international civil aviation radio is realized, whi
ch establishes a foundation for independent development of civil aviation ACARS
digital communication system. |
