Study on Frequency-Shift
Signal Demodulation
Using Gabor Transforming |
| |
| Abstract: | In order to
overcome the disadvantage of frequency-shift signal demodulation in time domain and
frequency domain and realize the reliable, accurate demodulation of frequency-shift
signal, a frequency-shift demodulation method based on Gabor transformation is proposed in
this paper. By means of computer simulation, the upper-frequency and down-frequency of
frequency-shift signal are demodulated accurately by using Gabor transforming,and
combining with FFT, the frequency-shift signal demodulation can be realized . |
