ofdm 程序，包括了信道估计以及相应的算法设计，是理解ofdm好的版本。(fodm It has included the channel estimate as well as the corresponding algorithm design, understands the ofdm good edition )

用 matlab 编写的高斯随机表面的生成(using Matlab prepared by the surface of the Gaussian random generation)

说明：  比较好的学习资料 适合于初学者来学习来使用(Better learning materials suitable for beginners to learn to use)

此程序先由Butterworth高通滤波器滤波图像,后用sobel算子程序进行边缘检测,效果不错!(this procedure first Butterworth high-pass filter images, After segmentation operator subroutine used for edge detection, good results!)

针对传统教学中出现的问题,分析在通信原理教学和实验中采用Matlab软件的可行性,提出在通信原理的课堂教学和实验教学中采用Matlab软件,不但能提高教学的有效性,而且可以加深学生对理论知识的理解和感性认识。 更多还原 (The traditional teaching of the problems, analyze the feasibility of using Matlab software teaching in communication theory and experiment, the proposed use of Matlab software in the classroom and laboratory teaching communication theory, not only can improve the effectiveness of teaching and students can deepen the understanding of theoretical knowledge and perceptions. More Restore)

说明：  实现两个指数信号的卷积，通过绘制出两个输入的指数信号的图形进行卷积后的图形说明卷积的作用。(Convolution of two exponential signals to achieve, by drawing out the index of the two input signals after convolution graphics graphic illustration of the role of convolution.)

This is the demo file for L1 adaptive controller with unknown parameter, unknown disturbance, unknown control effectiveness: dot x(t) = Ax(t) + b(omega u(t) + heta(t)^ op x(t) + sigma(t)) DoSims.m: This script initializes the model parameters, run the simulation. You can split the parts you need and do the simulations according to your interest. L1Model_sec2.mdl:the implementation of the system. Refer to the following paper for background: C. Cao, and N. Hovakimyan, “L1 adaptive controller for systems with unknown time-varying parameters and disturbances in the presence of non-zero trajectory initialization error”, International Journal of Control, Vol. 81, No. 7, 1147–1161, July 2008

格子BLOTZMANN方法，二维圆柱绕流的实现(Lattice BLOTZMANN method, two-dimensional flow around a cylinder to achieve)

基于互功率谱的时延估计，计算目标和海洋回波的功率谱密度,一个很有用的程序。( Based on the time delay estimation of power spectrum, Calculating a target and ocean echo power spectral density, A very useful program.)
