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
(This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)
