本文讨论LDPC 码及其在802.16 协议中的应用,并使用基于矢量阵列的因子图实现方法对其进行解码,仿真表明该码字是一种性能优秀的备选码字,使用该解码方法是可行的。【关键字】:低密度校验码,无线城域网,IEEE802.16,正交频分复用物理层【Abstract】:This paper discusses LDPC and its application in IEEE802.16. An array based factor graph implementation method is applied in the decoding of the code. The experimental result demonstrates that LDPC in IEEE 802.16, as one of the optional channel coding schemes, has very good performance with this decoding method.【Key Words】:LDPC,WMAN,IEEE802.16,OFDM PHY
