摘要 W iMAX采用了很多新的技术,其中LDPC码是其采用的关键技术之一。文中介绍了W iMAX中IEEE802.16e标准OFDMA物理层采用的LDPC码的编码技术,阐述了码结构和编码方式,并分析了其在加性高斯白噪声(AWGN)和ITU-3信道下的纠错性能。 Many new technologies have been applied in WiMAX and LDPC (low- density paritycheck) code is one of the most important technologies. This paper introduces the LDPC code used in IEEE802.16e OFDMA PHY layer, describes its structure and encoding method, and analyses its errorcorrecting performance under AWGN and ITU -3 channels.
