摘要
在OFDM系统中给出了基于全相位快速傅里叶变换的脉冲成形技术抑制PAPR算法.该算法将原始数据序列和成形脉冲矩阵相乘产生新序列,使多载波的各子载波符号间具有一定的相关性,从而改善信号的PAPR特性.建立了该算法在全相位OFDM系统中的数学模型,仿真验证了该算法有良好的PAPR抑制性能.
A method was provided to reduce the PAPR,which was based on all-phase FFT and pulse shaping technology.The new pulse sequences in this method can be generated by multiplying the raw data sequence and the forming pulse matrices,so that a certain correlation can exist between sub-carrier symbols of the multi-carriers.A mathematical model was set up for this method in the all-phase OFDM systems.Some simulations showed that the method can reduce PAPR very well.
