Data Transmittion: Data and Computer Communications

jmsn是一个完整的JAVA应用程序，下载解压后可以直接运行，运行的界面跟微软的MSN Messenger很类似，包括操作上都非常一致，如果你的操作系统是Linux或者其他那都可以直接用它来替代微软的程序。另外一个是msnm-lib，这个就是我们今天要介绍的API，它仅仅是一个开发包，在jmsn组件中已经包含了这个包。 -jmsn is a complete Java application that can be downloaded directly unpacked run, run interface with Microsoft"s MSN Messenger is very similar, including the operation are very consistent, if you are running Linux or other it can be directly used it to replace Microsoft"s procedures. Another one is msnm-lib, today we are introduced to the API, it is merely a development kits, in jmsn already contains components of the package.

fifty years of coding theory，一篇经典的讲述纠错编码的IEEE文档，适合纠错编码读者阅读。里面详细讲述的纠错编码的发展史，包括BCH、RS、卷积码、Turbo码等编码-fifty years of coding theory, a classical error-correcting code on the IEEE document, suitable for error-correcting code readers. Which describe in detail the history of the development of error correction coding, including BCH, RS, convolutional codes, Turbo codes encoding

NRF2401无线模块，STM32程序实现了数据双向通信.它分为接收和发送两部分，发送时发送的源程序，接收是接收的源程序，分别设置了俩个文件夹。nrf24l01在stm32的模块上，通过spi接口连接，实行通信，最终实现两块单独的stm32模块实现短距离的无线通信，速度高，功耗小。

Polarization beam splitters and 3dB couplers are used to construct a home-made90 ° optical hybrid, by  which polarization diversity optical coherent receiver is carried out with single-ended detection.A10Gb / s oscillation multiplexed differential phase shift keying (DPSK) signal is transmitted through280km Standard single- mode fiber (SSMF) using erbium-doped fiber amplifier (EDFA) amplification, and no error bits are measured in th result.
