用costas环实现载波同步。假设发送信号载波频率为3.563Mhz，本地初始频率为3.5628Mhz。程序中直接给出了环路滤波器的参数C1,C2。(this is synchoronization on time recovery basing on matlab)

通信工程方面的matlab电子书！希望对大家学习有用！(Communications engineering matlab book! We want to learn useful!)

比较全面的介绍了matlab对各种格式文件（包括.cdf等科学格式）的读写操作(More comprehensive description of the matlab files of various formats (including the cdf scientific format) read and write operations)

设计一个60阶的滤波器，要求设计的滤波器0~π/8的幅度为1，在π/8~2π/8的幅度为1/2，在2π/8~4π/8的幅度响应为1/4，在4π/8~6π/8的幅度响应为1/6，在6π/8~π的响应为1/8，并且画出理想滤波器和设计得到的理想滤波器的幅度频率和响应进行比较(Design of a 60-order filter designed filter 0 ~~ π/8 the amplitude is 1, the π/8 ~ 2π/8 the amplitude is 1/2, 2π/8 ~ 4π/8 amplitude response is 1/4, 4π/8 ~ 6π/8 the amplitude response of 1/6, 6π/8 ~ π response of 1/8, and draw the ideal filters and design of an ideal filter amplitude frequency and response to compare)

使用matlab编写的各种类型的遗传算法，每一种都有注释说明 可以复制到M文件中运行(Matlab prepared using various types of genetic algorithms, each with explanatory notes can be copied to M to run in files)

matlab程序，有关分岔图，主要是ode45(matlab procedures, the bifurcation diagram, mainly ode45)

MATLAB是美国MathWorks公司推出的一种可视化的科学计算软件，目前在国内外比较流行(MathWorks MATLAB is a US company launched a visualization in scientific computing software, the more popular at home and abroad)

说明：  简易SSB设计 有详细的报告和说明，可以作为参考(Simple SSB detailed design reports and notes, can be used as reference)

雷达系统分析与设计使用MATLAB第二版 Pdf(Radar Systems Analysis and Design Using MATLAB Second Edition Pdf)

本程序基于“图像模式识别—VC++技术实现”写就，实现了线性和非线性手写数字识别。 程序主文件是homework.m 具体实现可以参考程序内注释。 (this is a matalb programme,in order to recognise the number writtern by yourself. it include homework.m,homework.fig,Getfeature.m,losstab.m,losstab.fig,samplelib.m,samplelib.fig,save_sample.m,save_sample.fig)
