摘　　要：正交频分多址(OFDMA)是以正交频分复用(OFDM)调制为基础的新一代多址技术,具有很高的带宽利用率。文章介绍了它的基本原理,然后简单介绍了它在移动宽带无线接入中的应用,主要是关于信道编码,链路自适应技术,多天线技术。Orthogonal frequency division multiple access （OFDMA）, which has a high bandwidth availability is a new multiple access based on OFDM. In this paper, the principle of OFDMA is described and its application to mobile broadband wireless access is presented with focus on the channel coding, link adaptation technology, multi-antenna technology.
