摘　　要：数字通信越来越广泛的应用于政治、军事、商业等各项领域中,因此,对数据传输的可靠性的要求日益增长。自香农发表重要的香农定理以来,在寻求逼近香农极限的纠错编码的道路上,人们做出了不懈的努力。文章介绍了一种特殊的线性分组码LDPC码的结构,归纳了比较常见的几种LDPC码的编码方案,并对LDPC码的应用现状和发展趋势进行了介绍。Digital Communication is widely used in many areas, such as political, military, commercial and so on. As a result, the data reliability should be increasingly improved. After Shannon＇ s publisment of his famous Shannon Theory, the people have made great effort to find a better Error Control Coding whose performance is approaching to Shannon Limit. This paper describes the structure of a special linear block code LDPC. Then it summarizes some common coding principles of LDPC and shows the current application and development trend for LDPC.
