| Abstract: | Gabor tmnfformation is one of the time - frequency analysis and it is the improvement of FFT via short windows. In this paper, Gabor transformation is introduced to solve the problem of identifying the modulation format of an incoming signal. By means of compurer simulations and the theories analysis, the features of ASK, FSK and PSK is extracted. At the end, it proposes a modulation recognition algorithm and give results of the computer simulations. |
