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.

digital watermarking is a process by which a user-specified
signal is hidden or embedded into another signal , for
example digital content such as electronic documents, images,
sounds and video [2]. The use of digital video applications
such as video-conferencing, digital television, digital cinema,
distance learning, videophone, and video-on-demand has
grown very rapidly over the last few years. Today it is much
easier for the digital data owners to transfer multimedia data
over the internet, and hence the data could be perfectly
duplicated and rapidly redistributed on a large scale. Thus, the
importance of copyright protection for multimedia data has
become more critical. Digital watermarking is an effective way
to protect the copyright of multimedia data even after its
transmission there is urgent demand for techniques to protect
the original digital data and to prevent unauthorized
duplication or tampering.
