一种基于IDFT和PTS结合降低OOFDM系统PAPR的新方法

摘要

A method of combining Inverse discrete fourier transform (IDFT) and Partial transmit sequence (PTS) to decrease the peak average power ratio (PAPR) and a modified PTS (MLCC-PTS) scheme are proposed . It is shown by simulation that this method can improve the PAPR performance and lower the computational complexity.%提出了一种将逆离散傅立叶变换(Inverse Discrete Fourier Transform,IDFT)和PTS结合降低系统PAPR的方法,并针对PTS方法计算复杂度高的缺点,提出了一种改进的PTS算法.仿真结果表明,该方法可获得更好的PAPR性能和更高的计算效率.
