一、实验目的 通过本实验，了解信号估计的最小二乘法原理。 二、实验要求 1．导入受噪声污染的高斯信号数据，并绘制该信号。 2．推导高斯信号最小二乘法估计公式。 3．利用估计公式估计高斯信号的参数（幅值、均值和方程）。 4．画出估计出的高斯信号。(First, the purpose of the experiment Through this experiment, we know the least square method of signal estimation. Two. Experimental requirements 1. import noise contaminated Gauss signal data and draw the signal. 2. derivation of Gauss signal least squares estimation formula. 3. estimate the parameters of the Gauss signal (amplitude, mean and equation) by using the estimation formula. 4. draw the estimated Gauss signal.)
