摘要 OFDM(正交频分复用)是一种高效的传输技术,将被广泛地应用于下一代无线通信系统中。简单介绍了OFDM的概念,并详细阐述了OFDM系统的各种同步算法,包括时间同步算法,频率同步算法和时间频率联合同步算法。 OFDM (Orthogonal Frequency Division Multiplexing) is a kind of transmission techniques with high efficiency , which will be widely used in the next generation wireless communication systems. This article gives a brief introduction to the concept of OFDM.Detailed description is devoted on prevalent synchronization algorithms in OFDM systems, including time, frequency and united synchronization algorithms.
