A full tutorial about matlab (learn matlab from scratch)

线性调频信号的时域，幅频等有关的程序，成功运行(Chirp signal in time domain, amplitude and frequency and other relevant procedures, successful operation)

说明：  矩阵QR分解，采用householder方法。输入矩阵，返回分解参量，QR decomposition(QR decomposition)

数字信号处理中，用matlab编写fft,实现fft的功能(Digital signal processing using matlab fft, fft functionality)

通过MONTE GARLO仿真，说明一个使用二进制FSK并受到最坏部分频带干扰破坏的FH数字通信系统的性能。(MONTE GARLO through the simulation shows that the use of a binary FSK and are subject to the worst part of band interference and sabotage by FH digital communication system performance.)

matlab经典教程 内容为5个ppt文件 对于初学者不错(matlab program elements for the classic 5 ppt file good for beginners)

详细的介绍了UKF算法在matlab中的实现过程，并有matlab测试例子，适合UKF初学者(Described in detail in the UKF algorithm in matlab implementation process, and matlab test case for beginners UKF)

说明：  Bpsk在瑞利衰落信道下的仿真模型。simulink实现。可以通过仿真看到瑞利衰落信道对于bpsk性能的影响。并且可以比较rayleigh信道和AWGN信道下bpsk的性能。(Bpsk in Rayleigh fading channel simulation model. Simulink achieve. Simulation can see Rayleigh fading channels for BPSK performance impact. And to be compared Rayleigh Channel and AWGN under BPSK performance.)

该函数用来计算任意函数的一阶偏导数(数值方法),小波包分析提取振动信号中的特征频率，可以提取一幅图中想要的目标。( This function is used to calculate the arbitrary function of th)

在分析最小均方自适应滤波器(LMSAF)均方误差(MSE)的收敛性时，文献常用统计自相关矩阵代替瞬时自相关矩阵以简化分析，由此得出的收敛条件比较粗糙。本程序指出：不相关高斯输入情况下，无需如上简化，可依据高斯阶矩因式分解定理得到确切的MSE收敛条件，相应的失调表式能更准确地预报失调(In the analysis of LMS adaptive filter (LMSAF) the mean square error (MSE) convergence, the literature commonly used statistical correlation matrix instead of the instantaneous correlation matrix to simplify the analysis, it follows that the convergence conditions are relatively rough. This procedure pointed out: not related to the Gaussian input case, no simplification above may be based on the Gaussian moment factoring theorem to the exact order of MSE convergence conditions, the corresponding offset table style to a more accurate prediction of disorder)
