Joint Modulation Format Identification and Frequency Offset Estimation Based on Superimposed LFM Signal and FrFT

We propose a novel technique for joint modulation format identification and frequency offset (FO) estimation. The linear frequency modulation signal which is obtained by a direct current signal and Fractional Fourier Transform (FrFT) is superimposed on the data symbols to mark and identify the modul...
