摘要
未来的移动通信系统需要能够以最低的代价(带宽、功率、复杂性)来为各种用户提供高质量的宽带业务。这就需要有适于无线信道的传输技术来支持。正交频分复用(OFDM)技术就是适应这种信道环境的传输技术。目前OFDM技术还有很多关键问题有待解决。只有解决了这些问题,OFDM才能得到真正的应用。主要研究其中一个主要问题,就是利用限幅法减小OFDM信号峰平比(PAPR)问题。
In the future, mobile communication systems need to be able to at minimum cost （bandwidth, power, complexity）for a variety of users with high-quality broadband services. This requires the transmission technology for wireless channel to support. Orthogonal Frequency Division Multiplexing （OFDM） technology is to adapt to this channel of transmission technology environment. Currently, there are a lot of key issues about OFDM technology to be resolved. Only by addressing these issues, OFDM can be a real application. This paper studies one of the main problems that is using limiting law to reduce the PAPR of OFDM.
