Abstract

Schemes of demodulation for aircraft communications addressing and reporting system (ACARS) signal is presented in this paper. On the basis of in-depth study of the technology agreement about ACARS signal, the characteristic of ACARS signal is analyzed. A demodulation approach based on power spectrum estimation is described. According to the theoretical analysis, it can effectively restrain the white noise. At last the demodulation performance of this scheme is simulated with Monte Carlo method. Compared with the schemes of traditional non-coherent demodulation and differential demodulation, the spectrum estimation demodulation scheme has a lower BER, and its demodulation performance has been significantly improved, it has some practical application value.
