在OFDM技术中,PAPR(峰平比)过大的问题一直是人们研究的热点;作者利用一种新的CI/OFDM结构,通过选择合适的频率偏移,达到降低OFDM信号的峰平比的目的。通过对比分析了这种结构的可行性和有效性,并对其进行系统仿真。
In the OFDM technology, PAPR (peak-to-peak ratio) is always a hot research topic. The authors use a new CI / OFDM structure to reduce the peak-to-average ratio of OFDM signals by choosing the appropriate frequency offset purpose. By comparing and analyzing the feasibility and effectiveness of this kind of structure, and simulating it systematically.
