Compressive sampling is an emerging technique that promises to effectively recover a sparse signal from far fewer measurements than its dimension. The compressive sampling theory assures almost an exact recovery of a sparse signal if the signal is se

稀疏傅里叶变换算法利用了数字信号处理，特别是高斯和多尔夫-切比雪夫滤波器的技术。与传统的解决方法不同，对于这个问题我们的算法是不迭代的。也就是说，它用一种类似绘制/流式算法的方式“一次”识别并估计k个最大系数，而并非估计“大”系数以及在提示下相减、递归。-Sparse Fast Fourier Transform (SFFT) is a class of sub-linear time algorithms for computing the discrete Fourier transfo
