Modified Interleaved Partitioning PTS Method for PAPR Reduction in OFDM System

摘要

摘要: 该文首先证明在交织分割部分传输序列方法(IPTS)中，由于待选传输序列的非独立性而造成IPTS性能较差；为此，借助于对部分数据子块进行共轭运算来有效地增加IPTS算法中独立待选传输序列的个数，从而提高IPTS算法的性能。仿真结果表明，通过增加独立待选传输序列的个数，提出的改进IPTS (MIPTS)能够以较小的运算量达到(针对离散信号)或优于(针对连续信号) APTS算法性能。

Abstract: It is firstly proved that the non-independence among the candidates used in the Interleaved partitioning Partial Transmit Sequences (IPTS) results in the lower performance of IPTS, compared to the Adjacent partitioning PTS (APTS). More independent candidates can be created and better performance can be gained using subblocks and their conjugate versions in the proposed Modified IPTS (MIPTS). The simulation results show the MIPTS has similar PAPR reduction performance as APTS without over-sampling or is superior to APTS with over-sampling.
