Abstract :
This paper presents a BFSK demodulation method using discrete short-time Fourier transform (DSTFT). The method discusses the BFSK signal in time-frequency domain, which is different from conventional demodulation methods. The principle of demodulation and a new code synchronization algorithm are given in the paper, different window functions are tried during the simulation, which bring different demodulated performance. And the test results indicates the demodulation is all right.
