硕士学位论文:LDPC码在瑞利衰落信道中的性能分析 信道编码技术可以带来编码增益，节省宝贵的功率资源，己经成为现代数字 通信系统中必不可少的关键技术。LDPC码采用低复杂度的迭代译码算法，且具有 逼近香农限的性能.由于LDPC码具有诸多优点，它在信息可靠传输中的良好应 用前景己经引起学术界和rr业界的高度重视，成为当今信道编码领域最受瞩目的 研究热点之一。 本文主要探讨了LDPC码在瑞利衰落信道中的性能，基于LDPC码的分组空 时码系统，以及基于LDPC码的正交频分复用系统.-master"s degree thesis : LDPC codes in Rayleigh fading channels Performance Analysis channel coding technology can bring coding gain, Power saving valuable resources have become modern digital communication systems essential to the critical technologies. LDPC low complexity of the iterative decoding algorithm, having approximation Shannon limit performance. Because LDPC has many advantages, It reliable transmission of information in the application of good prospects has been caused rr academia and industry are taking, become the channel coding areas of the most watched one of the hot spots. This paper mainly discusses the LDPC Rayleigh fading channels in the performance Based on LDPC a space-time coding system, and based on LDPC

操作系统有所耳闻，它是微软已推出的三种操作系统内核之一，是一种实时操作系统。虽然它是一种实时操作系统，但是从96年发布v1.0到现在，它的主要用途都在民用领域，比如Pocket PC、SmartPhone、Automation。不像VxWorks，应用于航空航天、军事等领域。现在linux、VxWorks厂商也都看好嵌入式民用市场，激烈竞争在所难免。我看好Windows CE，因为微软在PC领域实在太强，用户也早已熟悉了微软的产品，把PC下的技术移植到嵌入式领域，首先在操作界面方面就占了上风。 -operating systems have heard, it is Microsoft has launched three of the operating system kernel, is a real-time operating system. Although it is a real-time operating system, but from the 96 released v1.0 now, which are mainly used in civilian areas, such as Pocket PC, SmartPhone, Automation. Like VxWorks, used in aerospace, military and other fields. Now Linux, VxWorks manufacturers are optimistic about embedded civilian market, fierce competition is inevitable. I like Windows CE, Microsoft in the PC field is too strong, users are already familiar with Microsoft products, the PC technology into the embedded field in the first operation on the interface prevailed.

对于做串口程序的人来说，简直就是雪中送炭-Serial port to do the procedure for anyone who is simply a temporary relief

用C编写的GPS时间采集程序，对于对时间精度要求很高系统值得借鉴- GPS time gathering procedure compiles which with C, regarding is worth to the time precision request very high system profiting from

应用背景采用多线程串口通信，占用系统资源极小，自动获取系统串口（实际、虚拟、usb、串口服务器等），开一个程序可以开启两个串口通信界面，尤其方便自发自收，能够自动保存数据，方便多串口调试尤其是单片机开发者使用关键技术本程序采用多线程串口通信类cxComm.h，通过注册表自动获取系统串口（实际、虚拟、usb、串口服务器等），可读取最大256串口号，支持中文发送接收，支持ascii码和16进制通信

由于Java具有跨平台、代码可移植性、安全高效等广泛而强大的功能，因而在开发网络分布式应用的时候，可以用它自身的机制实现分布式计算，一种基于Java的远程方法调用(RMI)为我们开发企业分布式应用提供了行之有效的解决方案。-As the Java cross-platform code portability, security, efficiency and so strong and broad features, and thus in the development of networks of distributed applications, they can use it to realize its own mechanism for distributed computing, a Java-based remote method invocation ( RMI) for distributed application development companies, we provide effective solutions.
