计算有空气孔介质光子晶体的色散曲线，供大家交流，互相学习(Calculated free pore Photonic crystal dispersion curves for all to exchange, learn from each other)

维Logistic映射 x(n+1)=μx(n)(1-x(n)) 在3. 57 <μ < 4 的参数区域内,系统存在混沌吸引子 (Dimensional Logistic map x (n+1) = μx (n) (1-x (n)) in 3. 57 < μ < 4 parameters in the region, the systems Chaotic attractor)

输入一个任意长的数字序列，使用幅度调制法调制，然后使用包络检波法解调(Enter an arbitrarily long sequence of numbers, use the modulation amplitude modulation method, and then use the envelope detection method demodulation)

说明：  通过优化的遗传算法来优化支持向量机的参数，很好用。(The parameters of support vector machine are optimized by optimized genetic algorithm, which is very useful.)

应用matlab产生用正弦信号调制的模拟PPM信号，并给出了功率谱密度(Matlab sinusoidal signal generated by application of the analog PPM signal modulation, and gives the power spectral density)

matlab大量绘图简称，大量实例保证教会，matlab语言。(matlab graphics-intensive referred to as a large number of instances to ensure that the church, matlab language.)

自己编写的基于nlms的回波消除算法，直接能运行(I have written based nlms echo cancellation algorithm can be run directly)

OFDM通信系统,QPSK映射，最终统计误比特率并画图(OFDM communication system)

运筹学模型的MATLAB实现，附有程序源码(MATLAB realization of operations research model, with program source code)
