fft
本文提出了一种采用六项余弦偶次幂窗三峰插值的算法来对电网谐波进行检测与分析。该算法通过分析电网信号加窗后傅里叶变换的频域表达式，利用谐波频点附近的三根离散频谱的幅值确定谐波谱线的准确位置，进而得到电网谐波的相关参数频率、幅值及相位的计算公式，最后再对其进行加权修正，从而进一步的提高检测的准确度和有效性。( this paper proposes an approach for power network harmonic detection and analysis based on six even order cosine window and triple-spectrum-line interpolation. Through analyzing the adding window signal fourier transform in the frequency domain expression, using amplitude of three discrete spectrum near the harmonic frequency point to determine the accurate position of the harmonic spectrum and get the calculation formula of related parameters of the power network harmonic such as frequency, amplitude and phase, the algorithm further enhances the accuracy and effectiveness by using weighted correction.)

GaussianClutterPowerSpectrumEstimation
本程序已被本人整理到WORD文档中，编程语言为MATLAB，程序中首先利用非递归法产生滤波器系数，生成相关高斯杂波，直接对杂波信号作FFT变换，结果取模平方后除以长度N,即可得到杂波的功率谱，设计参数皆在文档中表明。此程序已经验证是正确可执行的，并能生成图形，值得下载！( This program has been organized into WORD document I, the programming language MATLAB, the program produced the first method using non-recursive filter coefficients to generate the relevant Gaussian clutter, clutter signals directly to FFT transform, the result after the square modulus divided by the length of the N, can be obtained the power spectrum of clutter, design parameters are indicated in the document. This procedure has been verified is correct executable, and can generate the graph, it is worth to download!)
