A research on the non-coherent demodulation method of the underwater 2FSK signal

摘要：

This paper presents a non-coherent demodulation method of 2FSK signal based on instantaneous frequency, which uses two median filters to smooth the instantaneous frequency sequences. And this method is proved useful to realize code synchronization. When the code rate is 1kbps, the ber is about 10-5.

关键词： 2FSK non-coherent demodulation instantaneous frequency underwater acoustic channel.
