摘要
同步是OFDM系统中非常关键的问题。文章先分析了OFDM系统不同的同步技术,在此基础上讨论了OFDM的时频同步算法,最后指出了不同同步算法的应用。只要合理地选择适当的同步算法,就可以实现OFDM系统的同步。
OFDM is a multi-carrier digital modulation technology, with the development of multi-media services especially the requirement of wireless environment by beyond 3G, OFDM has attracted much attention. OFDM has been considered as the principal technology for beyond 3G mobile communications.
