Research on the Algorithms for Fourier Digital Computation of Fractional Transform
Abstract：As the Fractional Fourier Transform （FrFT） can be seen as an unified time-frequency transform,it has been a powerful tool which can be widely used in such signal processing fields as： radar, communication, sonar, and so on. The fast computation of the FrFT is the a key problem of the practical applications. In this paper, the definition of the FrFT is introduced and several typical algorithms were ana- lyzed. Then, A twc~phase implementation of the fractional Fourier transform described by Adhermar Bultheel is studied. By comparison,it has advantages of high precision and fast speed, which can improve the real-time performance in engineering field.
