| Abstract: | Based on the mathematical characteristic of MSK signal,this paper proposed a new digital demodulation method for MSK signal by using within symbol differential method.Detailed illumination of the algorithm and the code-error rate on white noise channel are presented.Simulation result shows that it is simple and effective.Compared to the traditional demodulating algorithms,this method is non-sensitive to the carrier frequency-offset and phase shift,could be applied in communication and recon fields. |
