CAsyncSocket完成的客户端和服务端通讯示例程序源代码-CAsyncSocket_C/SSocket

关于GPS定位方程式的讲述，是台北的Jeff写的，我把它编程了文档，发给大家，一起拿来学习。-GPS positioning on the formula described is written in Taipei, Jeff, and I recommend it programmers the document, distributed to you, used to study together.

著名的串口构件，很容易自己使用，支持多线程。-Famous serial widget, it s very easy for use and sustain several thread.

本程序是一个直接扩频序列仿真包。需要matlab中安装了simulink才可以使用。-This procedure is a direct sequence spread spectrum packet simulation. Need matlab installed can only be used simulink.

一个开放源码的免费的P2P客户端软件，用于文件交流，支持中文搜索。它和Neo-Modus公司的Direct Connect使用同一个通讯协议，但比它功能更加强大，可以同时登陆很多服务器。开放源码，绿色软件，也没有广告条。DC是分散服务器型的，服务器端也是免费的，因此适合同一个地域内的用户飞速交换文件。目前全世界有上万个服务器，通过DC共享的资料超过5,000,000GB。-a free open-source peer-to-peer client software for document exchange, support Chinese search. It Neo-Modus Direct Connect companies use the same communication protocol, but higher than its more powerful, while landing many servers. Open source software green, nor of the advertising. DC is decentralized server-based, server-side is also free, making it suitable to the region with a rapid exchange of user documentation. There are now more than 10,000 items of servers, DC by sharing information over 5,000,000 GB.

网络消息通讯，很有趣的一个程序，是我们实践课的时候编的，对初学者很有用-news network communications, a very interesting process, the practical lesson of our time series, useful for beginners

利用哈夫曼编码进行通信可以大大提高通信信道利用率，缩短信息传输时间，降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码；在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双工传输信息的信道），每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.

再贡献一份基于osip 协议栈的用户代理，enumphone，可以研究一下-a further contribution osip protocol stack based on the user agent, enumphone can study

WCDMA基本原理教材,中兴公司培训教材。3G时代，学通信的要赶快赶上啊！-WCDMA the basic principles of teaching materials, ZTE training materials. 3G era, learning to communicate to quickly catch up with ah!

MATLAB程序的仿真比较。随后，针对QPsK，详细讨论了其基本原理和具体的实现算法，并进行了仿真验证，然后选用HSP502巧数字上变频芯片和HSP50214B数字下变频芯片，设计了数字调制、解调器的实现方案。最后，作为对整个数字视频图像传输系统的宏观认识，利用M户JLAB中的实时建模仿真Simullnk库对典型的视频图像传输系统一数字视频广播系统(D vB)，进行了建模、仿真和初步的分析，结果表明:在高斯白噪声的传输环境下，系统采取的一系列抗干扰措施，包括内、外码级联的信道纠错编码和先进的调制技术(o FDM)等，保证了信源信息传输的有效进行。-MATLAB simulation comparison. Then, against QPsK to discuss in detail the basic principles and specific algorithm, a simulation test, and then choose the cleverest HSP502 figures HSP50214B frequency chips and digital down conversion chips, the design of digital modulation, demodulation for the realization of the program.MJLABSimullnk(D vB):Andean white noise transmission environment, the system adopted a series of anti-jamming measures, including internal and external codes Cascade Channel advanced error correction coding and modulation techniques (o FDM), ensuring a source of information for the effective transmission.
