A good book on WiMAX networks.

分别用三种不同的差分近似公式（前向差分、后项差分和中心差分）来技术函数的近似值(Respectively with three different difference approximation formula (forward difference, backward difference and central difference) approximation to the technical function)

dc motor pid modeled

this is a project for voice recognition in matlab using vector quantization.

模式识别。PCA实例，经调试可用，希望能帮到需要的人。(Pattern Recognition. PCA instance, debugging is available, I hope to help people in need.)

说明：  读入一段mp3音乐，将音乐进行FM调制，在噪声信道中传输，接收端解调音乐(Reads period mp3 music, music to FM modulation, the transmission in a noisy channel, the receiving terminal demodulates the music)

说明：  ga-pls选取特征波长，能过有效减少建模所需要的波长。(Ga-pls can effectively reduce the wavelength required for modeling by selecting the characteristic wavelength)

说明：  进行预测或分类后，用此来进行误差计算，得到误差图(After forecasting or classifying, the error figure can be obtained by calculating the error with this method.)

黑体辐射光谱与波长关系，前两阶第二类变型贝塞尔曲线，光波导芯层导模的传播常数，啁啾光栅光谱，LP模的归一化辐射曲线(Blackbody radiation spectrum versus wavelength, the former two-stage variant of the second category Bezier curves, optical waveguide core guided mode propagation constant, chirped grating spectrometer, LP mode normalized radiation curve)

蚁群算法程序，我用过的人，根据具体情况，修改一些参数就可得结果(Ant colony algorithm program, I used people, depending on the circumstances, the results obtained can modify some parameters)
