OFDMA系统频率同步算法综述-Orthogonal frequency division multiple access (OFDMA) has recently attracted vast research attention from both academia and industry and has become part of new emerging standards for broadband wireless access. Even though the OFDMA concept is simple in its basic principle, the design of a practical OFDMA system is far from being a trivial task. Synchronization represents one of the most challenging issues and plays a major role in the physical layer design. The goal of this paper is to provide a comprehensive survey of the latest results in the field of synchronization for OFDMA systems, with tutorial objectives foremost. After quantifying the effects of synchronization errors on the system performance, we review some common methods to achieve timing and frequency alignment in a downlink transmission. We then consider the uplink case, where synchronization is made particularly difficult by the fact that each user’s signal is characterized by different timing and frequency errors, and the base station has thus to estimate a relatively large number of unknown parameters. A second difficulty is related to how the estimated parameters must be employed to correct the uplink timing and frequency errors. The paper concludes with a comparison of the reviewed synchronization schemes in an OFDMA scenario inspired by the IEEE 802.16 standard for wireless metropolitan area networks.

正交频分多址接入(OFDMA)是OFDM(正交频分复用)调制的一种形式,它针对多用户通信进行了优化,尤其是蜂窝电话和其它移动设备。   它是针对蜂窝电话长期演进(LTE)的最合适调制方案。在这种演变的过程中, OFDMA的名称变为高速正交频分复用分组接入(HSOPA)。OFDMA的变量由WiMAX论坛选为调制方案,后来又根据IEEE针对IEEE 802.16-2004(固话)和802.12e(移动)WiMAX的标准进行了标准化。   与CDMA(码分多真址接入)宽带CDMA及通用移动通信系统(UMTS)这类3G调制方案相比,它的好处在于具有更高的频谱效率和更好的抗衰落性能。对于低数据率用户
