这是pi_4_DQPSK的MATLAB仿真源程序，很好的仿真了这种数字调制和解调(This is pi_4_DQPSK the MATLAB simulation of source, a good simulation of this kind of digital modulation and demodulation)

说明：  经验模态分解(Empirical Mode Decomposition,EMD)法是黄锷(N. E. Huang)在美国国家宇航局与其他人于1998年创造性地提出的一种新型自适应信号时频处理方法，特别适用于非线性非平稳信号的分析处理。(Empirical Mode Decomposition)

这是ofdm的MATLAB仿真源程序，很好用(This is the MATLAB simulation ofdm source, useful)

简单的PCA主元分析源码，自己编写，亲测可用(Simple PCA principal component analysis of the source code, I have written pro-test available)

GN25L98 GPON 的芯片手册 详细记载了芯片的使用方法(GN25L98 GPON chip manual Detailed the use of the chip)

说明：  使用libsvm进行三分类，svm多分类可以类似编程(Use libsvm for three categories, svm classification can be more similar to programming)

提供一个matlab程序，功能是将被Delta-Sigma调制器调制过的信号解调出来。(Provide a matlab procedures, functions will be Delta-Sigma modulator modulated signal demodulated.)

重采样MATLAB程序2例参考程序。用于对信号进行不同采样频谱的采样(resampling)

NOISYMPC Basic Predictive Control with noise and distrubances. (Script file) Implements unconstrained MPC for stable SISO discrete-time system defined as LTI object. Simulation of measurement noise, and of unmeasured input and output disturbances is included.
