一种利用平均值降低PAPR的新方法
《甘肃科技》2011年第15期50-52,共3页张进新 万毅 
目前,降低OFDM系统高峰均功率比(PAPR)的方法,有SLM(Partial Transmit Sequences),PTS(Partial trans-mitted sequence),Companding等。通过对PTS、Companding法的研究,笔者提出了一种新的利用信号平均值降低PA-PR的方法。在这种方法中...

Combined DCT and Companding for PAPR Reduction in OFDM Signals被引量：2
《Journal of Signal and Information Processing》2011年第2期100-104,共5页Zhongpeng Wang 
The high peak-to-average (PAPR) is one of the serious problems in the application of OFDM technology. The com-panding transform approach is a very attractive technique to reduce PAPR, but large PAPR reduction leads to...
