High performance sparse Fast Fourier Transform using OpenACC
… Sparse Fast Fourier Transform (sFFT) is a recent algorithm developed by Hassanieh et al. at MIT for Discrete Fourier Transforms on signals with a sparse frequency domain. A reference implementation of the algorithm exists and proves that the sFFT can be faster than modern FFT libraries for signals …
