LTE Uplink Multiple Access System DFT-S-GMC and DFT-S-OFDM Comparison Study

本文在分析两种LTE上行多址接入系统信号产生的基础上,对DFT-S-GMC和DFT-S-OFDM系统信号的峰均比性能和同步性能进行了仿真分析。从仿真结果分析得出两种系统信号的峰均比性能相当,DFT-S-OFDM-D同步效果相对较好的结论。研究结果可为下一代移动通信系统选择上行多址方案提供参考。

Based on the analysis of two multiple access uplinks LTE signal generation systems, we has carried on the simulation analysis to DFT-S-GMC and the DFT-S-OFDM system signal＇s PAPR performance and the synchronized performance. The sinmlation results from the two systems we have come to the PAPR rather than performance, DFT-S-OFDM-D effect is relatively good synchronization conclusions. The findings may provide the reference for the next generation mobile communication system choice upward multiple access plans.
