LDPC码的高性能信道纠错码理论

摘要

Since the 1960s channel coding theory has been put forward,how to construct the a analog communication channel capacity has become the main topic of scholars all over the world to study,and reflect the communication ability of a major problem. For half a century,the scientific construction of the Shannon condition algorithm based on two main lines is proposed.The superior performance of the proposed LDPC codes to attract people continue to explore its application in various fields:in broadband access network application, multilevel coding based on binary LDPC calculation method through the simulation experiment proved the method in the process of transmission channel of high performance algorithm.In the algorithm record model,the high throughput rate and the complex LDPC decoding scheme are combined in the magnetic recording.%自从上世纪60年代信道编码理论提出至今，就如何构建一个模拟通信信道容量问题成为了各国学者努力研究的主要课题，并且形成了通信能力体现的一个主要问题。半个世纪以来，各国科学通过构造以两条主线为基础提出的香农条件算法。提出的LDPC码的优异性能吸引人们不断探讨它在各个领域的应用：在宽带接入网中的应用方面，基于二元LDPC的多电平编码计算方法，通过仿真实验证明了该方法在信道传输过程中的高性能算法。在进行算法记录模型方面，用磁记录中的高吞吐率和繁杂LDPC译码方案结合进行。
