摘要 针对OFDM系统高峰均比问题,提出一种基于时频二维处理的方法,该方法利用时隙结构系统中的时域自由度和频域相位旋转获得峰均比降低增益。为了降低原始算法的复杂度,给出了两种基于时域移位和随机选择次优算法。仿真结果表明,在峰均比降低概率为10-4处,提出的方案能够获得至少3 dB的峰均比降低增益;与多符号SLM算法相比,随机选择次优算法在峰均比降低概率为10-4处,能够获得近1 dB的峰均比降低增益。 This paper introduced PAPR reduction approach termed time permutation and phase rotation (TPPR) for OFDM systems,which exploited the additional freedom degrees of time domain symbols in one timeslot to obtain additional PAPR reduction gains. For complexity reduction, proposed two suboptimal schemes time shifting (TS-TPPR) and random selecting ( RS-TPPR). Simulation results show that, at the 10^-4 PAPR reduction probability ,the methods can obtain at least 3 dB PAPR reduction gains, and compared to multi-symbol SLM, RS-TPPR can provide about ldB performance gains with the same complexity.
