Question

求翻译，谢谢！急用啊！在线等的哦！

本论文首先介绍了DFT以及进行谱分析等基础知识，介绍了 FFT 的“栅栏”效应以及运算量的分析，对MATLAB中的FFT算法进行理解。本论文对频率估计的常用方法进行了回顾，包括最大拟然算法，Rife算法以及修正的Rife算法，MUSIC算法。本论文最后提出了用离散频谱的比值校正法估计信号的频率幅度和相位角，并用MATLAB进行计算机仿真分析，运用比值校正法估计信号的频率幅度和相位，其精度高，误差小，实现简单方便。

Answer 1

This paper first introduces the basic knowledge of DFT and spectrum analysis, introduces the "fence" effect and the computation of FFT analysis, understanding the FFT algorithm in MATLAB. This paper reviewed the commonly used method to estimate the frequency, including the maximum quasi likelihood algorithm, Rife algorithm and modified Rife, the MUSIC algorithm. This paper finally put forward with the ratio of discrete spectrum correction method to estimate signal frequency amplitude and phase Angle, the computer simulation analysis with MATLAB, use ratio correction method estimate signal frequency amplitude and phase of its high precision, small error, implementation is simple and convenient.
