摘要
首先简要介绍了正交频分复用(OFDM)技术的产生背景,然后重点介绍了OFDM的基本原理实现框图,并对中频信号做了相应的理论推导。最后对OFDM的性能做了详细的描述,其中主要介绍了OFDM的优点和缺点及SC-FDE。
The latest developments for Orthogonal Frequency Division Multiplexing（OFDM） are introduced. In the first place,the background of OFDM is introduced. Secondly, the principle technique are presented, including implemental scheme, and the intermediate frequency signal is explained in theory. At last, the capability analysis for OFDM are discussed, the advan rage and disadvantage of OFDM and SC - FDE are introduced in detail.
