FFT
利用FFT估计正弦信号的频率,要估计一个叠加了高斯白噪声的正弦信号 的频率 ,可以通过对x(n)做傅里叶变换,得到频谱图,找出幅度的最大值对应的频率值 ,进行多次变换,求出均方误差 。改变信噪比SNR,通过仿真可以得出随着信噪比增加,均方误差减小。(Sinusoidal signal using FFT frequency estimation, to estimate a Gaussian white noise superimposed on the frequency of sinusoidal signals, can be achieved by x (n) be the Fourier transform to get spectrum to identify the magnitude of the frequency value corresponding to the maximum , several transformations, find the mean square error. Change the signal to noise ratio SNR, the simulation can be drawn as the SNR increases, the mean square error decreases.)
