Abstract


An intelligent recognition algorithm for subcarrier based on combining Fourier transform wavelet and multi-resolution analysis was proposed in the paper. The proposed method can recognize each component from the mixed signal fast and accurately. Also the recognized signals were identified based on the estimations of subcarrier code rate and frequency. The proposed subcarrier recognition method can effectively recognize multiple signals from the subcarrier signal according to the simulation results. Moreover, the method exhibits the advantages of high recognition precision and strong noise immunity.
