基于MATLAB,各种信道的估计方法，共13种(Estimation_of_Kinds_of_Channels(MATLAB))

说明：  用中心差分实现一维小波变换，可自行作改进(with center differential to achieve a peacekeeping wavelet transform, the discretion to make improvements)

关于空间谱估计算法的一些性能比较，大家可以参考一下，看一看(On the spatial spectrum estimation performance comparison of the coding )

总结了自己关于通信原理学习的一下认识,希望大家多交流(about Communication Fundamentals in my side)

该程序能够通过使用Allan方差算法来分析陀螺噪声。(The program can be through the use of Allan variance algorithm to analyze the gyro noise.)

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)
