摘要:正交频分复用(OFDM)是第四代移动通信的核心技术。该文首先简要介绍了OFDM基本原理,重点研究了理想同步情 况下,保护时隙(CP)和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系 统模型的基础上,用MATLAB语言实现了整个系统的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,保 护时隙、信道估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。 (O FDM is the key techno logy of 4G in the field of mobile comm unication.In this article O FDM ba sic p rinc ip le is briefly in troduced.Then,the influence of CP and d iffe rent channe l e stim a tion on the system pe rfo rm ance is emp ha tica lly analyzed respectively in Gauss and R ayle igh fading channe ls in the cond ition of ideal synchronization.B e sides,based on the given system mode l O FDM system is compu te r sim u la ted w ith MA TLAB language and the refe rentia l design p rocedure is given.Fina lly,the B ER cu rves of CP and channe l e stim ation a re given and comp ared.The conclusion is sa tisfac to ry. )
