Introduction to OFDMA in LTE
Author(s): 
Pages: 25-28
Year: Issue:  2
Journal: Data Communications

Keyword:  长期演进(LTE)正交频分复用多址(OFDMA)快速傅立叶变换(FFT)WCDMA;
Abstract: LTE多址技术与WCDMA中的多址技术不同.在LTE系统中,下行链路多址技术建立在正交频分复用多址(OFDMA)的基础上,而上行链路多址技术则是基于单载波频分多址(SC-FDMA)技术的.文章分析了OFDMA实现过程,描述了OFDMA发射机和接收机结构与原理,讨论了OFDMA的优势与挑战.
