WebApr 12, 2024 · The Chirp-Z transform (CZT) is a generalization of discrete Fourier transform (DFT). The Chirp-Z transform was proposed by Rabiner et al. in 1969 . However, Chirp-Z transform has problem in inverse calculation. In 2024, Vladimir Sukhoy and Alexander Stoytchev solved the fifty-year long inverse problem of the Chirp-Z … WebThis algorithm has been named the chirp z-transform algorithm. Using this algorithm one can efficiently evaluate the z-transform at M points in the z-plane which lie on circular or spiral contours beginning at any arbitrary point in the z-plane. The angular spacing of the points is an arbitrary constant; M and N are arbitrary integers.

Webdiscrete Fourier transform can be conveniently generalised using the z-transform and z-plane. CTA adds flexibility to the DFT by allowing a high resolution subsampling of an arbitrary arch on the unit circle. It still maintains N log N performance. CZT, the generalised CTA, evaluates the z-transform along a spiral contour of the z-plane. WebMar 4, 2014 · Previously, we proposed channel prediction methods employing the chirp z-transform (CZT) with a linear extrapolation as well as a Lagrange extrapolation of frequency-domain parameters.
