The Aircraft Communication Addressing and Reporting System (ACARS) is playing an increasingly important role to guarantee the safety and the efficiency of aircraft, so more effective method of receiving is necessary. The modulation of the ACARS system is MSK, the aim of this paper is to find a better demodulation method for the signal of ACARS. The characteristic of mapping relationship between code-element and the signal of waveform is analyzed. A new demodulation method is proposed based on the characteristic. Compared to the traditional demodulation method, it has a more simple structure. A simulation is made to verify its performance in the background of Gaussian noise. The comparison with traditional methods is also be made. Finally the benefit and weakness of this method is discussed.
