摘要:
 针对部分传输序列法（PTS）计算复杂度过高的问题，提出了一种峰均功率比降低的方法。该方法联合交错分割与随机分割策略，提高数据块分组效率；采用多数据块联合优化的新型相位因子，提升获得最小峰均功率比的概率；利用引入惯性权值的粒子群算法优化最佳相位因子寻优过程，降低算法复杂度。理论分析和仿真实验表明，该方法具有更优的峰均功率比抑制性能，且计算复杂度不高。
Abstract:
 In order to solve the problem of high computational complexity of partial transmission sequence (PTS), a new peak to average power ratio (PAPR) reduction method is proposed. This method combines staggered partitioning and random partitioning strategies to improve the efficiency of data block grouping. A new phase factor optimized by multiple data blocks is used to increase the possibility of obtaining the minimum peak-to-average power ratio. The particle swarm algorithm with the introduction of inertia weight is used to optimize the optimization process of the optimal phase factor and reduce the complexity of the algorithm. Theoretical analysis and simulation experiments show that this method has better peak-to-average power ratio suppression performance, and the computational complexity is not high.
