说明: 本论文以OFDM系统为基础,介绍了OFDM系统的基本原理,以及使用OFDM技术的优势所在,并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时,着重阐述了OFDM系统在不同信道环境和不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道,在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能,其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础上,用MATLAB进行仿真,最后做出误码性能的分析和比较。
(This paper has OFDM systems based on OFDM systems introduces the basic principles and the use of the advantages of OFDM technology, and to look towards the future of wireless mobile technology development prospects. In a brief OFDM principles, while focusing on the OFDM system under different channel environments and different modes to achieve the error performance. Mainly include the OFDM system in additive white Gaussian channel, in the additive white Gaussian channel and multi-path interference of two different channel environment, the system BER performance, the latter of which also studied the system in a guard interval and non-protected BER performance comparison interval. The theoretical basis of the analysis, using MATLAB simulation, finally make a bit error performance analysis and comparison.)
