Modulation and demodulation QAM

说明：  里面有滑模控制教材的所有程序,很有参考价值(Sliding mode control materials inside all of the programs)

color tracking green n red

Wind Power Maximizer

在matlab环境下编程实现了应用模糊控制理论整定PID控制器参数，并对已知模型进行阶跃响应仿真实验。(Matlab programming environment in the realization of the control theory of fuzzy PID controller tuning parameters, known model and step response simulation.)

说明：  文件中含有大量的vc++语言和MATLAB语言的源代码，并附带有运算结果(File contains a large number of vc++ language and MATLAB language source code, together with an operation result)

在计算机上产生一组实验数据，首先产生一段零均值白噪声数据u（n）,令功率为 ，让u(n)通过一个三阶FIR： 得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形； (2)得出真实功率谱密度 . (3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。 (On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

分别利用EMD和小波进行降噪，并进行对比分析，内附经典论文。(Were carried out using the EMD and wavelet noise reduction, and a comparative analysis, containing classic papers.)

滤波器矩阵综合程序，本程序可以根据性能要求综合目标滤波器的n+2维耦合矩阵(filter synthesize)

这可是有关通信方面的MATLAB非常好的资料，而且很权威，是我们学习的号东西，里面有关通信方面的M文件十分齐全(This is related to communications MATLAB very good information, and are the authority, is something we can learn its inside on the communications papers are full of M)
