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
