  • Abstract
    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.
