| 摘 要： | An iterative algorithm is developed for the Hilbert transform based on FFT using the phase in-formation of modulated signal.The feature of this iterative algorithm is frequency shifting on apart of non-integral frequency in a modulated signal,and the final result of the orthogonal signalwith less pollution caused by the leakage phenomenon is obtained.The algorithm has been appliedto estimate envelope,center frequency and initial phase,including simulation and engineering ex-amples.
