摘　　要：介绍了OFDM技术的发展现状及应用前景。针对OFDM系统峰均比较高的缺点,研究降低PAPR的各种算法,分析与比较不同算法的优势与不足,并对降低峰均比的压扩变换法、PTS算法以及SLM算法进行了计算机仿真,同时给出不同算法下的系统误码率性能仿真结果,指出扰码类算法在降低PAPR方面的优势。仿真结果对PAPR问题的研究具有借鉴意义。The development of OFDM technology as well as its applications are introduced. As to the problem of high PAPR, it makes research on different methods of reducing PAPR. Advantages and shortcuts are analysed and compared. Simulations which are based on the companding,PTS and SLM algorithms are carried out. The BF.R results are also under analysis. And the disturbed code algriothm is superior compared with the other algriothms. The simulation results may be of reference value for the further research of the PAPR problem.
