Minimizing Communication in the Multidimensional FFT [PDF]

open access: yesSIAM Journal on Scientific Computing, 2023
We present a parallel algorithm for the fast Fourier transform (FFT) in higher dimensions. This algorithm generalizes the cyclic-to-cyclic one-dimensional parallel algorithm to a cyclic-to-cyclic multidimensional parallel algorithm while retaining the property of needing only a single all-to-all communication step.

A pre-FFT equalizer design for application to Hiperlan/2 [PDF]

open access: yes, 2000
Use of a pre-FFT Equaliser (PFE) has been previously proposed as a method for either improving the efficiency of OFDM radio modems or increasing the excess delay spread that they are capable of operating under.

Collective-Optimized FFTs

open access: yesCoRR, 2023
This paper measures the impact of the various alltoallv methods. Results are analyzed within Beatnik, a Z-model solver that is bottlenecked by HeFFTe and representative of applications that rely on FFTs.

FFT-ESPRIT: a kernel-based subspace estimator for frequency super-resolution at quasi-linear time complexity

open access: yes, 2023
We introduce two FFT-based ESPRIT algorithms for line spectral estimation which have lower time complexities than the original ESPRIT algorithm's O(N^3).

The Frobenius FFT

open access: yesProceedings of the 2017 ACM International Symposium on Symbolic and Algebraic Computation, 2017
Let Fq be the finite field with q elements and let ω be a primitive n-th root of unity in an extension field Fqd of Fq. Given a polynomial P ∈ Fq [x] of degree less than n, we will show that its discrete Fourier transform (P (ω0), ..., P (ωn - 1)) ∈ Fqdn can be computed essentially d times faster than the discrete Fourier transform of a polynomial Q ...
