optimization-design
用最优化方法解决最优化问题的技术称为最优化技术，它包含两个方面的内容：
(1)建立数学模型，即用数学语言来描述最优化问题。模型中的数学关系式反映了最优化问题所要达到的目标和各种约束条件；
(2)数学求解，数学模型建好以后，选择合理的最优化方法进行求解。
(With optimization method to solve the optimization technology, called the optimum technology, it contains two aspects: (1) established the mathematical model, which is the mathematical language to describe the optimization problem. Model of the mathematical relationship reflects the optimal problem to achieve and all constraint conditions (2) solving mathematics, mathematical model built after, choice of reasonable solution of the optimization method.)

HHT
把HHT和神经网络结合起来，识别出是否故障。对于HHT变换，这里用到的是它的IMF分解，然后用能量理论来判别哪些模组是虚假分量，哪些是是真实分量。对于EMD分解后的谱进行特征提取 ，利用的理论基础就是模糊熵。计算出真实 分量的模糊熵，作为输入层；输出层为两个神经元，为0（故障 ）1（正常 （正常 ）判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)

DPD_sim
Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects.
This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts:
1)Analog imperfection compensation for the direct upconversion transmitter
2)Design a DPD based on a memory polynomial predistorter
3)Performance evaluation via a number of parameters such as:EVM,PSD,SNR,
