本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo，给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。 由于对于码块长较大的情形仿真需要较长时间，源码包也给出了部分分量码多项式的仿真结果，可直接用于绘图。 源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献，以及本人对通信系统中迭代译码过程分析技术综述的小论文，希望对大家有所帮助。(This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help.)

TOA算法，可以计算三维点的坐标，这个方法很好用哦(TOA algorithm, you can calculate the coordinates of 3D points, this method is very easy to use Oh)

NETI@home is an open-source software package, named after the widely popular http://setiathome.ssl.berkeley.edu/, that collects network performance statistics from end-systems. It has been written for and tested on the Windows, Linux, Mac OS X, and Solaris operating systems, with testing for other operating systems to be completed soon. NETI@home is designed to run on end-user machines and will collect various statistics about Internet performance. These statistics will then be sent to a server at the Georgia Institute of Technology (Georgia Tech), where they will be collected and made publicly available. We believe that this tool will give researchers much needed data on the end-to-end performance of the Internet, as measured by end-users. Our basic approach is to sniff packets sent to and received by the host and infer performance metrics based on these observed packets. NETI@home users are able to select a privacy level that will determine what types of data will be gathered, and wh
