A New Method Based on Scaled Particle Swarm Optimisation to Reduce the PAPR of FBMC System

  • 摘要: 部分传输序列(Partial Transfer Sequence, PTS)是滤波器组多载波(Filter Bank Multicarrier,FBMC)降低峰均功率比(Peak-to-Average Power Ratio, PAPR)的有效方法之一,但PTS存在计算复杂度高等问题。本文提出了一种基于PTS的新方法,采用一种奇数分割法(Odd-PTS),并在此基础上引入了一种基于比例因子的粒子群优化(Scaled Particle Swarm Optimisation, SPSO)算法,通过加入比例因子克服PSO算法收敛速度不足等缺点。该方法不仅降低了系统的PAPR性能还降低了计算复杂度,并显著提高了频谱利用率。通过仿真验证了本文方法的有效性。
