Study of the method of discrete STFT demodulation for the FSK signal
Feng Xiao · Jounal of Xidian University · 2001
This paper presents a new digital demodulation method of the FSK Signal, which is based on the Short Time Discrete Fourier Transform. The FSK signal is discussed in the time frequency plane, and the statistical methods are used to evaluate its frequency and code width. A typical example about demodulation of 8FSK is given, and the influence of different windows is discussed, and the simulative results of this demodulation method under different signal to noise ratios (SNR) are presented finally.
