摘要

快速傅里叶变换（FFT）在非同步采样的情况下会产生频谱泄露和栅栏效应

存在较大误差

无法获得高精度谐波和间谐波参数。利用加窗插值算法可以有效减小非同步采样的影响

而窗函数的特性和所考虑峰值附近谱线的范围是提高准确度的关键所在。为此

本文提出一种基于六项最快旁瓣衰减速度窗和六谱线插值的算法。通过仿真实验

对比了不同的窗函数和不同插值算法

验证了该方法的可行性和高精度性。

Abstract

Fast Fourier transform（FFT）

in case of non-synchronous sampling

can produce spectral leakage and fence effects

have large error and have no way to obtain high-precision harmonic and inter-harmonic parameters. The use of windowed interpolation algorithm can reduce effectively the influence of nonsynchronous sampling

while the characteristics of the window function and consideration of the range of spectral line near the peak are the key to improve the accuracy. For this purpose

in this paper an algorithm based on six term window functions with maximum side lobe decay speed and six-line interpolation is proposed. Different window functions and different interpolation algorithms are compared through simulationexperimentandthefeasibilityandhighaccuracyofthemethodisverified.
