大气层内航天器飞行动力学matlab仿真模型(The atmosphere inside the spacecraft flight dynamics matlab simulation model)

说明：  针对一般的粒子群优化(PSO)学习算法中存在的容易陷入局部最优和搜索精度不高的缺点,对改进型PSO算法进行研究。由于惯性权重系数ω对算法是否会陷入局部最优起到关键的作用,因此,通过改变惯性权重ω的选择,对惯性权重系数采取线性减小的方法,引入改进型的PSO算法。采用改进的PSO算法对PID控制器进行参数优化并把得到的最优参数应用于控制系统中进行仿真。仿真实验结果表明:改进型PSO算法不会陷入局部最优,能得到全局最优的PID控制器的参数,并使得控制系统的性能指标达到最优,控制系统具有较好的鲁棒性。(Aiming at the shortcomings of general PSO learning algorithm, which is easy to fall into local optimum and low search precision, the improved PSO algorithm is studied)

可擴展的OFDMA引擎的WiMAX, 裡頭有詳細的OFDMA 物理層的記述(A Scalable OFDMA Engine for WiMAX)

基于多频（三频）的频谱校正（相位差法），达到校正相位的目的，已经过调试。(Based on multi-frequency (C-band) spectrum correction (phase difference method) to achieve the purpose of the correction phase, has been testing.)

By using these matlab codes a simple BPSK modulation can be implemented. The format used is Polar NRZ

说明：  有用的matlab源，大家看一下是否有用啦。或许对你有帮助哦。(Matlab useful source, we look at whether it is useful to you. May be helpful to you, oh.)

详细介绍了matlab中的p文件，asv文件以及mat文件，对matlab初学者者有用(Described in detail in matlab p files, asv files and mat files, useful to beginners on matlab)

Dilution of precision part 2

选择“BreastCancer”数据集，使用支持向量机(SVM)对其进行分类。作为对比，第一次对特征集直接进行支持向量机分类，第二次对特征集进行主成分分析法的特征提取后，再对特征提取后的特征集进行支持向量机分类。并且对比和分析了两次分类的结果。(The BreastCancer data set is selected and classified by Support Vector Machine (SVM). For comparison, the first time the feature set is classified directly by support vector machine, the second time the feature set is extracted by principal component analysis, and then the feature set is classified by support vector machine. The results of the two classifications are compared and analyzed.)
