说明：  Matlab是一种简洁而容易入手的编程工具，对于学电子的同学在学习《数字信号处理》（清华大学版）的过程中可随课本的学习，联系matlab 一些基本的程序。(Matlab is a simple and easy to start programming tools for students learning electronic learning &quot Digital Signal Processing&quot (Tsinghua University, version) in the process of learning can be as textbooks, contact matlab some of the basic procedures.)

twinkle twinkle little star. how i wonder what you are. up above the world so high. like a diamond in the sky.

根据系统的输入和输出，辨识系统的的传递函数。该系统为6阶系统，通过降阶降为2阶后，加入状态反馈和状态观测器，调整参数使2阶系统稳定，最后用于控制原6阶系统。阶跃响应和bode图效果都不错。(Based on the input and output of the system, the transfer function of the system is identified. The system is a 6 order system. After the order is reduced to 2 order, the system is added with the state feedback and the state observer, which adjusts the parameters to make the 2 order system stable. Finally, it is used to control the original 6 order system. Step response and Bode figure results are good.)

包括最小二乘法、SVM、神经网络、1_k近邻法,包括调制，解调，信噪比计算，最小均方误差（MMSE）的算法，一种流形学习算法（很好用），D-S证据理论数据融合，单径或多径瑞利衰落信道仿真，利用贝叶斯原理估计混合logit模型的参数。( Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Includes the modulation, demodulation, signal to noise ratio calculation, Minimum mean square error (MMSE) algorithm, A fluid manifold learning algorithm (good use), D-S evidence theory data fusion, Single path or multipath Rayleigh fading channel simulation, Bayesian parameter estimation principle mixed logit model.)

有关多采样率转换问题，本文介绍了多采样率转换的MATLAB实现以及基础理论。(Multi-sample-rate conversion on the issue, this paper introduce a number of sample-rate conversion of MATLAB as well as realize the basis of the theory.)

仿真波束宽度和经典music算法最小分辨角度，从而计算锐化比(Simulation beam width and angle of the classical music minimum resolution algorithm to calculate the ratio of sharpening)
