正交频分复用(OFDM: Orthogonal Frequency Division Multiplexing)是一种多载波调制技术，早在20世纪60年代就已经提出了OFDM的概念，不过由于实现复杂度高，大家并不怎么关注，之后随着DFT(离散傅立叶变化)、FFT(快速傅立叶变换)的提出以及DSP芯片技术的发展，极大减少了OFDM实现复杂度和成本，OFDM逐步在通信领域得到了广泛的应用，并且成为了高速移动通信中的主流技术。OFDM使用相互重叠但正交的窄带传输数据，相比传统的多载波系统具有更高的频谱利用率。3gpp选择OFDM作为LTE下行数据传输制式。由于OFDM信号是多个子载波信号的叠加，所
