Center node: "nearly optimal sparse fourier transform"
  Abstract: We consider the problem of computing the k-sparse approximation to the discrete Fourier transform of an n-dimensional signal. We show: #R##N#* An O(k log n)-time randomized algorithm for the case where the input signal has at most k non-zero Fourier coefficients, and #R##N#* An O(k log n log(n/k))-time randomized algorithm for general input signals. #R##N#Both algorithms achieve o(n log n) time, and thus improve over the Fast Fourier Transform, for any k = o(n). They are the first known algorithms that satisfy this property. Also, if one assumes that the Fast Fourier Transform is optimal, the algorithm for the exactly k-sparse case is optimal for any k = n^{\Omega(1)}. #R##N#We complement our algorithmic results by showing that any algorithm for computing the sparse Fourier transform of a general signal must use at least \Omega(k log(n/k)/ log log n) signal samples, even if it is allowed to perform adaptive sampling.
