摘要 正交频分复用(OFDM)是4G移动通信系统中备受关注的关键技术之一,具有较强的抗干扰能力和较高的频谱利用率。在对OFDM系统的基本思想进行介绍的基础上,对该系统的优点和缺点分别进行了分析,并较详细地阐述了OFDM系统中的关键技术及存在的问题。 The Orthogonal Frequency Division Multiplexing （OFDM） is one of the key technologies to which receive much attention in 4G mobile communication. It has strong anti - interfere capacity and high spectrum efficiency. Based on the introduction to the basic idea of OFDM system, the advantages and disadvantages are analyzed respectively. The key technologies and the existing problems in OFDM system are discussed in details.
