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

各种L2数据网具有不同的通信协议与帧结构，其网络节点设备可以是各种类型的数据交换机（X.25、FR、Ethernet和ATM等分组交换机）；而L3数据网（IP网或internet）具有统一的TCP/IP通信协议和分组结构，全网采用统一格式的IP地址， 节点设备统一采用面向无连接的路由器。为便于理解，我们可以将L3数据网简单地理解为构建在L2数据网平台上的一个路由器网。-L2 data network with a variety of different communication protocol and frame structure, the network node device can be of various types of data switches (X.25, FR, Ethernet and ATM packet switches, etc.) and L3 data network (IP network or internet) have a unified TCP/IP communication protocol and packet structure, the whole network using a unified format for the IP address, node equipment reunification-oriented connectionless router. In order to facilitate understanding, we can L3 data network simply interpreted as a data network built on the L2 platform for a network router.
