The Aircraft Communication Addressing and Reporting System (ACARS) are 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.
