针对基于正交频分复用的大规模多用户多输入多输出系统中存在的峰均功率比问题，提出了一种新的自适应音调预留方案。提出的ATR方案的核心思想是在具有最大PAPR的天线上迭代地执行音调预留(TR)方案。仿真结果表明，ATR方案比传统的TR方案具有更好的PAPR降低性能和更低的计算复杂度。
In this letter, a novel adaptive tone reservation (ATR) scheme is proposed for the orthogonal frequency division multiplexing-based large-scale multiuser multiple-input multiple-output systems to deal with the inherent peak-to-average power ratio (PAPR) problem. The key idea of the proposed ATR scheme is to iteratively perform the tone reservation (TR) scheme on the antenna with the maximum PAPR. Simulation results validate that the ATR scheme offers better PAPR reduction performance and lower computational complexity than the conventional TR scheme.
