WebJan 12, 2012 · We consider the problem of computing the k-sparse approximation to the discrete Fourier transform of an n-dimensional signal. We show: * An O(k log n)-time randomized algorithm for the case where the input signal has at most k non-zero Fourier coefficients, and * An O(k log n log(n/k))-time randomized algorithm for general input … WebFeb 12, 2024 · The BxBFFT's coding style gives better control over synthesis to avoid and resolve performance bottlenecks.
