| 摘 要： | 对载波干涉技术降低OFDM的峰均功率比方法进行改进。先对输入信号进行分组,使系统峰值功率得到明显降低,之后再对分组后的信号进行载波干涉。理论分析及仿真结果表明,提出的方法能使系统峰值功率有明显降低,进而达到了进一步的降低峰均功率比的目的。该方法算法简单、不产生失真,不用传送边带信息,易于与其他降低PAPR的技术相结合使用,具有较好的实用性。

| Abstract: | The method of reducing the peak-to-average power ratio (PAPR) with carrier-interferometry is improved in OFDM system.First we divide the input signal into several groups,which could reduce peak power significantly,and then use carrier-interferometry after grouping.The theoretical analysis and simulation results demonstrate that the scheme in the paper can reduce peak power significantly,and reduction of peak-to-average power ratio (PAPR) is also achieved further.The proposed method is simple,without distort... |
