摘要
正交频分复用(OFDM)系统中,有很多降低峰均比(PAPR)的方法,联合算法是其中的一个大类。系统研究了峰均功率比(PAPR)较高的原因,着重比较几种联合算法的降低峰均比的效果,并给予仿真说明比较。在现有PARR降低算法的基础上,深入研究了算法之间的最佳联合方法。通过理论对比和实际仿真,总结出较易实现和简便的联合算法。
Many methods could reduce PAPR,in OFDM system,and the combined algorithm is one of the major categories.The reasons for fairly high PAPR are analyzed,the effects of severat combined algorithms in reduction of PAPR are simwated and compared.Based on the existing PAPR-reduction algorithms,the optimal combinations of between the algorithms are studied.Finally,by theoretial analysis and simalation,the easily-implemented and convenient combined algorithms are concluded.
