    白噪声中单个正弦信号的频率检测与估计 产生,其中是一高斯白噪声,其均值为0,方差为1。用MUSIC方法估计观测数据中正弦波的频率,并给出白噪声方差()un2uσ 与复正弦波的振幅A的估计值。(A single frequency detection and estimation of the sinusoidal signal in white noise, which is a Gaussian white noise with mean 0 and variance 1. MUSIC method to estimate the frequency of sine wave in the observation data, and gives the white noise variance () estimated value of the the un2uσ complex sine wave amplitude A.)

    根据牛顿插值原理进行数据的拟合,附有牛顿插值原理和它的matlab的实现方法,有点简单了,但是过程中的好些地方还是值得学习的。(Newton interpolation carried out in accordance with the principle of data fitting, with Newton interpolation matlab principle and its realization method, a bit simple, but in the process of a number of places it is still worth learning.)
