A novel recursive Fourier transform for nonuniform sampled signals: application to heart rate variability spectrum estimation.
We present a novel method to iteratively calculate discrete Fourier transforms for discrete time signals with sample time intervals that may be widely nonuniform. The proposed recursive Fourier transform (RFT) does not require interpolation of the samples to uniform time intervals, and each iterativ...
