50HZ陷波器的介绍与作用，原理及简单的设计实验，与测试方法(50HZ introduction and notch filter functions, principles and simple design experiments, and test methods)

This is a simple position location algorithm using Least Square Estimation algorithm. Timing information is time of flight (TOA) of signal between Tx and Rx. This code generally describes the Positioning method, Also it plots final coordinate of node in 2D. All other information was inlcuded as comments in source code.

本程序可以正常下载，运行。线性分组码定义，对于长度为n的二进制分组码，可以表示成（n，k），通常用于前向纠错。在分组码中，监督位加到信息位之后，形成新码，在编码中，k个信息位，被编为n位长度，（n-k）个监督码的作用是实现检错和纠错。(linear block code)

核主成分分析方法是主成分分析的改进算法，其采用非线性方法提取主成分(Kernel principal component analysis method is an improved algorithm of principal component analysis, which uses a nonlinear principal components extracted)

国外最新的有关MATLAB方面的电子书籍，值得一读，推荐！(good book.)

一个基于BP神经网络预测的matlab小程序，可以参考一下(based on an artificial neural network to predict the Matlab small procedures that will make reference to)
