A Deterministic Sparse FFT for Functions with Structured Fourier Sparsity
In this paper a deterministic sparse Fourier transform algorithm is presented which breaks the quadratic-in-sparsity runtime bottleneck for a large class of periodic functions exhibiting structured frequency support. These functions include, e.g., the oft-considered set of block frequency sparse functions of the form
متن کاملFast Deterministic Distributed Algorithms for Sparse Spanners
This paper concerns the efficient construction of sparse and low stretch spanners for unweighted arbitrary graphs with n nodes. All previous deterministic distributed algorithms, for constant stretch spanners of o(n2) edges, have a running time Ω(n ) for some constant > 0 depending on the stretch. Our deterministic distributed algorithms construct constant stretch spanners of o(n2) edges in o(n...
متن کاملA sparse Prony FFT
We describe the application of Prony-like reconstruction methods to the problem of the sparse Fast Fourier transform (sFFT) [6]. In particular, we adapt both important parts of the sFFT, quasi random sampling and filtering techniques, to Prony-like methods.
متن کاملFFT Algorithms
The DFT usually arises as an approximation to the continuous Fourier transform when functions are sampled at discrete intervals in space or time. The naive evaluation of the discrete Fourier transform is a matrix-vector multiplication W~g, and would take O(N) operations for N data-points. The general principle of the Fast Fourier Transform algorithms is to use a divide-and-conquer strategy to f...
متن کاملContemporary View of Fft Algorithms
A large number of fast Fourier transform (FFT) algorithms exist for efficient computation of the discrete Fourier transform (DFT). In most previous benchmarking efforts, only the computation speed or the operations count have been used for assessing the efficiency of these algorithms. In this paper we provide a comprehensive comparison of several contemporary FFT algorithms on state-of-the-art ...
