Matlab code for the simulation of HF channel with Rayleigh fading

Finite element method introduction in matlab

svm的一种特征选择方法，基因选取算去，减少特征数量，减少运算时间，也可提高运算精度(svm a feature selection method, gene selection operator to reduce the number of features to reduce the computation time, but also can improve the calculation accuracy)

说明：  这个方案是非常基本的振幅调制和解调初学者实施。已作出评论。(This program constitutes of very basic amplitude modulation and demodulation implementation for beginners. Comments have been made. )

在matlab下进行滑模变结构控制仿真系统的研究。希望对研究控制的同志有帮助。本人做论文时写的(Matlab under the sliding mode variable structure control simulation system. I hope the study will help control comrades. I used to do paper)

past when the sample data was collected, the future predictions can also be expected to be right. Application of machine learning methods to large databases is called data mining. The analogy is that a large volume of earth and raw material is extracted from a mine, which when processed leads to a small amount of very precious material similarly in data mining, a large volume of data is processed to construct a simple model with valuable use, for example

本算法是TD-SCDMA中初始同步捕捉DwPTS下行同步导频时隙的仿真(TD-SCDMA initial synchronization capture DwPTS downlink slot synchronization Pilot Simulation)

介绍了我们常用的预测方法神经网络算法的理论知识(Common prediction methods of theoretical knowledge of the neural network algorithm)

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!
