| Abstract: | Taking LFM signal,biphase coded signal,FSK,single frequency of the RF signal as examples,this paper proposes an algorithm to achieve Modulation pattern recognition based on Two-Dimension Dispersed Fourier Transform aim at lacalization of existed algorithms.,we spend more effort on self-correlation matrix and analysing operation scale. Simulations is carried out to demonstrate the effectiveness of the proposed algorithm. |
