The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)

这里主要对LMS算法及一些改进的LMS算法（NLMS算法、变步长LMS算法、变换域LMS算法）之间的不同点进行了比较，在传统的LMS算法的基础上发展了LMS算法的应用。另一方面又从RLS算法的分析中对其与LMS算法的不同特性进行了比较，很值得研究！(The key players here and some of the LMS algorithm is an improved LMS algorithm (NLMS algorithm, variable step size LMS algorithm, transform domain LMS algorithm) the differences between the points of comparison, in the traditional LMS algorithm is developed on the basis of the LMS algorithm applications. On the other hand and from the analysis of RLS algorithm and LMS algorithm for its different characteristics were compared, it is worth studying!)

PCA主元分析是用于过程监测中的很好的方法(PCA principal component analysis is used to process monitoring in the good way)

K-MEANS 算法matlab版本 注释详尽(K-MEANS algorithm matlab detailed release notes)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。正所谓 一分钱一分货啊，优化效果不总是令人满意。(This procedure is the most basic particle swarm optimization procedures, using Matlab implementation, is very simple. Only a few dozen lines of code. One is the so-called sub-penny ah goods, and optimize the result is not always satisfactory.)

将采用训练函数 traingdx 和“提前停止”相结合的方法来训练 BP 网络，以提高 BP 网络的推广能力(Will use the training function traingdx and " stop ahead" a combination of methods to train BP network to improve the generalization ability of BP network)
