2. 设 是窄带信号,定义 是在 区间上均匀分布的随机相位。 是寬带信号,它是一个零均值、方差为1的白噪音信号e(n)激励一个线性滤波器而产生,其差分方程为 。
1) 计算 和 各自的自相关函数,并画出其函数图形。根据此选择合适的延时,以实现谱线增强。
2) 产生一个 序列。选择合适的 值。让 通过谱线增强器。画出输出信号 和误差信号e(n)的波形,并分别与 和 比较。
(Computer Experiments:
1. Consider an AR process x(n) defined by the difference equation
where v(n) is an additive white noise of zero mean and variance .The AR parameters and are both real valued:
a) Calculate the noise variance such that the AR process x(n) has unit variance .Hence , generate different realization of the process x (n).
b) Given the input x (n), an LMS filter of length M = 2 is used to estimate the unknown AR parameters and . The step size is assigned the value 0.05. Compute and plot the ensemble average curve of and by averaging the value of parameters and over an ensemble of 100 different realization of the filter. Calculate the time constant according to the experiment results and compare with the corresponded theoretical value.
c) For one realization of the LMS filter, compute the prediction error
And the two tap-weight errors
and
Using power spectral plots of , show that)

sheeell
The following Matlab project contains the source code and Matlab examples used for a pretty seashell gui. This GUI draws a seashell, using a parametric surface. The parameters of the seashell can be modified with sliders and buttons in the GUI. See also the seashell.m file, also on MATLAB Central (with no GUI).
The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there

捷联惯导系统放置在室内测试台上做静态测试,测试时间4500s。
1)取前180数据做粗对准(解析对准法);
2)取第181s~900s数据做精对准(Kalman滤波法);
3)从第901s开始做纯惯导解算;
4)用国军标的导航系统位置精度评价方法评估系统定位精度(分别计算CEP50 和 CEP95 下的定位精度)。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s.
1) take the first 180 data for rough alignment (analytical alignment method);
2) accurate alignment of 181s-900s data (Kalman filtering method);
3) pure inertial navigation solution is performed from 901s;
4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)
