摘　　要：综合研究正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)系统中资源分配和峰值平均功率比(Peak to Average Power Ratio,PAPR)抑制问题,提出一种OFDMA子载波分配与子载波预留(Tone Reservation,TR)技术联合优化方法。该方法利用部分子载波降低系统PAPR,同时对系统进行自适应子载波分配达到联合优化。仿真结果表明,该方法中系统的PAPR抑制效果和吞吐量参数能够同时得到优化。The Orthogonal Frequency Division Multiple Access(OFDMA)system is used to study the resource allocation and the Peak to Average Power Ratio(PAPR)suppression.A joint optimization method of OFDMA subcarrier allocation and Tone Reservation(TR)is proposed.In this method,the PAPR of the system is reduced by partial carrier,and the joint optimization is achieved by adaptive subcarrier allocation.The simulation results show that the PAPR suppression effect and throughput parameters of the system can be optimized simultaneously.
