...Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) AAFFT, implemented by Mark Iwen in 2008. This code is easy to use, and documented well, but not implemented very efficiently. It is much slower than it should be. 3.) GFFT, implemented by Ben Segal and Mark Iwen. This code is less easy to use, and also not terribly efficient. ...

libRfDsp is a collection of c++ tools for digital signal processing and simulation with a focus on RF/Microwave domain. The base data types are int, double and complex waveforms. Currently FFT, DDC, filtering and some basic operations are available.

This project is to implement a kind of educational program which will demonstrate FFT algorithm and help students better understand Fourier transformation.

For a given signal, pstool calculates a one-sided power spectrum, i.e. the portion of a signal's power falling within given frequency bins. This is done by employing a one-dimensional real-to-complex FFT routine on an MPI cluster.
