摘要

OFDM是4G在移动通信领域的关键技术。本文简要介绍了OFDM的基本原理。然后，重点分析了理想同步条件下高斯衰落信道和瑞利衰落信道下CP和不同信道估计对系统性能的影响。此外，在给定系统模型的基础上，利用MATLAB语言对OFDM系统进行了计算机仿真，给出了信道估计和信道估计的误码率曲线并进行了比较。

Matlab simulation and performance analysis of OFDM system

OFDM is the key technology of 4G in the field of mobile communication. In this article basic principle of OFDM is briefly introduced. Then, the influence of CP and different channel estimation on the system performance is emphatically analyzed respectively in Gauss and Rayleigh fading channels in the condition of ideal synchronization. Besides, based on the given system model OFDM system is computer simulated with MATLAB language, and the BER curves of CP and channel estimation are given and compared.
