摘　　要：近年来,正交频分多址接入系统做为一种新的多址接入技术受到了极大关注。在OFDMA中,相临的多个子载波被分配给不同的用户来为用户并行低速传输数据。子载波是相互间重叠且正交的,所以避免了载波间干扰的产生。文中介绍了向上链接子载波交织分配的OFDMA系统。Recently, Orthogonal Frequency Division Multiple Access(OFDMA)as a new multiple access technology has received a lot of attention. In OFDMA, closely spaced multiple subcarriers are assigned to different users for parallel data transmission. The subcarriers are overlapping but orthogonal to each other such that there is no ICI(inter-carrier interference). This paper introduces the receiver scheme for interleaved OFDMA uplink system.
