Fourier Transforms (and More) Using Light

Linear transforms — like a Fourier transform — are a key math tool in engineering and science. A team from UCLA recently published a paper describing how they used deep learning techniques to design ...

Computational Complexity of Fourier Transforms Over Finite Fields

In this paper we describe a method for computing the Discrete Fourier Transform (DFT) of a sequence of $n$ elements over a finite field $\mathrm{GF}(p^m)$ with a ...

Non-Power-of-Two FFT Circuit Designs Do Not Have to be Difficult

At the same time there are important disadvantages to using the power-of-two (P2) FFT, in particular limits on the number of reachable transform sizes that make it difficult to match data set sizes ...
