i want to crack this mdb file, plz help me

仿真对象如下： 其中， v( k )为服从N (0,1) 分布的白噪声。输入信号u ( k) 采用M 序列，幅度为 1。M 序列由 9 级移位寄存器产生，x(i)=x(i-4)⊕x(i-9)。 选择如下辨识模型： 加权阵取Λ = I。 衰减因子β = 0.98，数据长度 L = 402。 辨识结果与理论值比较，基本相同。辨识结果可信 (he simulation object is as follows: among them, v (k) to obey N (0, 1) distribution of white noise. The input signal u (k) using M sequence, amplitude is 1. M sequence by 9 level shift register generation, x (I) = x (I- 4) ⊕ x (I- 9). Choose the identification model: weighted array take Λ = I. Attenuation factor β = 0.98, the data length L = 402. Identify the theoretical calculation and comparison, basically the same. Identification results are reliable)

此代码是在matlab下开发，适应于GPS高程拟合，只需加载相关数据，方便好用(This code is developed in matlab to adapt in the fitting of GPS Elevation, just load the relevant data, easy-to-use)

电压暂降正周期有效值,是四案例工程中比较常见的算法。(t=0:0.0002:0.2 y=cos(100*pi*t) y1=0.5*cos(100*pi*t) y(200:600)=y1(200:600) for i=1:1:901 u(i)=sqrt(sum(y(i:i+99).^2)/100) end plot(u) xlable( 采样点数 ) ylable( u ) )

CS重构算法OMP算法。matlab源代码，。(CS reconstruction algorithm OMP)

信号包络，提出信号包络，便于观察信号波动过程，非常有用(Signal envelope, put forward the signal envelope, easy to observe the process of signal fluctuations, very useful)
