Abstract
An M-point Fractional Fourier is described using several 2M-points traditional Fourier transforms. The signal path is fed through a series of blocks including a first multiplier, a zero pad, an FFT, a second multiplier, an IFFT, a first half element, and a third multiplier. The first and third multipliers have as their other inputs a value exp(−jΠnα) for n=0:M−1, derived from the clock offset signal represented by α.
