Description: 提出了一种细化FFT的短时傅立叶变换(shorttimeFouriertransform,简称STFT)时频分析新方法.STFT实 质为加窗的傅立叶变换,在窗内数据满足平稳性条件下利用傅立叶变换获得频谱,并依据时间间隔移动窗函数最终得到时频表示.细化FFT在分析频率范围内具有较高的频率分辨率,将细化FFT应用于STFT的窗内数据,可有效提高STFT的时频聚集性-Proposed a frequency analysis of short-time Fourier transform FFT refinement (shorttimeFouriertransform, referred to as STFT) A new method. STFT essence of the windowed Fourier transform, the data within the window satisfies the stationary conditions spectrum obtained by Fourier transform, and based time interval finally get moving window function frequency representation. refinement FFT has a higher frequency resolution in the analysis of the frequency range, the refinement of the FFT applied STFT window data, which can effectively improve the STFT time-frequency aggregation

Description: 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
transform of a time domain signal which is sparse in the frequency domain, i.e. there are very few “large”
coefficients in the frequency domain. The algorithm was presented in [1]. As reported in that paper, experiments
with two C++ implementations of the algorithm (SFFT 1.0 and 2.0) demonstrates practical improvement in
the runtime over Fast Fourier Transform (FFT) for a wide range of signal sparsities.
