基于4G关键技术的OFDM及SC-FDE研究

摘要

In this paper, the basic principle of OFDM is introduced, and the problem of RAPP and the sensitivity to carrier frequency synchronization is discussed. The structure and function of this system is similar to the OFDM system, but it has no disadvantages of OFDM system. This paper also has a certain reference value for OFDM and SC-FDE system in Simulink environment.%文章阐述了OFDM的基本原理，依据多载波系统RAPP大和对载波频率同步敏感中的不足，对另一种单载波频域均衡系统进行介绍。这种均衡系统的结构和功能与OFDM系统相似，但其却没有OFDM系统具有的缺点。文章还在simulink环境下对OFDM及SC-FDE系统进行了建模仿真和分析，希望对相关行业有一定的参考价值。
