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,

说明: 稳健自适应波束形成,Wiley出版社,是一本有关MVDR波束形成稳健性分析的好书。(The latest research and developments in robust adaptive beamforming Recent work has made great strides toward devising robust adaptive beamformers that vastly improve signal strength against background noise and directional interference. This dynamic technology has diverse applications, including radar, sonar, acoustics, astronomy, seismology, communications, and medical imaging. There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids. Robust Adaptive Beamforming compiles the theories and work of leading researchers investigating various approaches in one comprehensive volume. Unlike previous efforts, these pioneering studies are based on theories that use an uncertainty set of the array steering vector. The researchers define their theories, explain their methodologies, and present their conclusions. Methods presented include: Coupling the standard Capon beamformers with a spher)

滑模变结构控制MATLAB仿真(第2版)仿真程序
滑模变结构控制本质上是一类特殊的非线性控制,其非线性表现为控制的不连续性,这种控制策略与其它控制的不同之处在于系统的“结构”并不固定,而是可以在动态过程中根据系统当前的状态(如偏差及其各阶导数等)有目的地不断变化,迫使系统按照预定“滑动模态”的状态轨迹运动。由于滑动模态可以进行设计且与对象参数及扰动无关,这就使得变结构控制具有快速响应、对参数变化及扰动不灵敏、无需系统在线辩识, 物理实现简单等优点。该方法的缺点在于当状态轨迹到达滑模面后,难于严格地沿着滑模面向着平衡点滑动,而是在滑模面两侧来回穿越,从而产生颤动,即抖振问题。

随机森林
说明: 随机森林算法与 Bagging 算法类似,均是基于 Bootstrap 方法重采样,产生多个训练集。不同的是,随机森林算法在构建决策树的时候,采用了随机选取分裂属性集的方法
本程序中,将乳腺肿瘤病灶组织的细胞核显微图像的 10 个量化特征作为模型的输入,良性乳腺肿瘤和恶性乳腺肿瘤作为模型的输出。用训练集数据进行随机森林分类器的创建,然后对测试集数据进行仿真测试,最后对测试结果进行分析。(Similar to bagging algorithm, random forest algorithm is based on bootstrap resampling to generate multiple training sets. The difference is that the random forest algorithm uses the method of randomly selecting the split attribute set when constructing the decision tree
In this program, 10 quantitative features of nuclear microscopic image of breast tumor tissue are taken as the input of the model, and the benign and malignant breast tumor are taken as the output of the model. The training set data is used to create the random forest classifier, then the test set data is simulated and the test results are analyzed.)
