摘　　要：首先介绍了FDSS调制技术降低峰均比(PAPR)的基本原理,然后设计了在5G上行DFT-S-OFDM波形上采用透明和非透明两种FDSS技术方案。通过仿真得出,这两种FDSS技术方案都可以有效降低π/2-BPSK调制的DFT-SOFDM波形信号的PAPR,因此可以提高信号的发射功率,进而提升系统解调性能。In order to reduce the signal PAPR to meet some technical requirements for 5G, the basic principle of FDSS modulation technique to reduce PAPR was introduced firstly. Then, two schemes of FDSS including the transparent mode and the non-transparent mode were designed on 5G uplink DFT-S-OFDM waveform. Simulation results show that the two FDSS schemes can effectively reduce the PAPR ofDFT-S-OFDM waveform signals modulated by n/2- BPSK. In conclusion, the two schemes not only increase the signal transmission power but also improve the system demodulation performance.
