摘　　要：在分析降低PAPR的常用算法的基础上,提出一种基于部分传输序列(PTS)算法和压扩变换(C变换)算法的联合算法。仿真结果表明所提联合算法能以较小的计算复杂度有效的降低OFDM系统的峰均比,算法具有一定的实用价值。OFDM techonology find application in the High-Definition TV system.But the high Peak-to-Average Power Ratio(PAPR) is a main drawback in OFDM system.This paper make researches on the usual algorithms of reducing PAPR and propose a combined algorithm which is based on the PTS algorithm and Companding algorithm.Simulations results indicate that the PAPR of OFDM system can be efficiently reduced with low computational complexity by using the practicable combined algorithm.
