摘要
本文针对OFDM系统存在着高峰均比的问题,提出了以部分传输序列法为基础来减少OFDM系统中的峰均比的方案,该方案是用分割法来最小化PAPR,最后用MATLAB对其仿真,PAPR显著减少,降低了变换器的复杂性,提高了线性放大器的利用效率.
Aiming at the problem of high PAPR value for OFDM system, this paper introduces a method of partial transmit sequence to reduce PAPR value. Part of the transmission sequence （PTS） algorithm divides the original input data into a combination of several same length of data block to minimize PAPR value. MATLAB simulation shows that PAPR value is reduced significantly,the complexity of the converter is reduced and the utilization efficiency of linear amplifier is improved.
