摘要 针对具有大量子载波的时域同步正交频分复用(TDS-OFDM)系统,提出了应用星座图扩展降低TDS-OFDM系统的峰均功率比(PAPR),同时增加保护间隔的能量以增大信号的平均功率,使得TDS-OFDM的PAPR进一步降低。最后给出了相应的仿真结果。 For time domain synchronous-OFDM(TDS-OFDM) systems with a large number of sub-channels, this paper proposed constellation extension to reduce the PAPR of TDS-OFDM. Synchronously, because of increasing the power of guard intervals to make the average power of TDS-OFDM increase, TDS-OFDM system can achieve lower PAPR. And the simulation results are given.
