OFDMA上行链路系统的频偏估计算法
Overview of carrier frequency offset estimation algorithm for OFDMA uplink
摘要
Abstract
Firstly the advantages and disadvantages of orthogonal frequency division multiple access (OFDMA) and the current application fileds are introduced in this paper. Then the development background and methods of carrier frequency off-set(CFO) estimation for OFDMA uplink are summarized and categorized. And the system diagram and the signal model of OFDMA uplink with carrier frequency offset is given. Furthermore, several typical frequency offset estimation algorithms are analyzed and discussed. Finally, the research directions and some key issues about frequency offset estimation of OFDMA uplink system are summarized.关键词
