抽象。针对光正交频分复用（OFDM）系统峰均功率比（PAPR）高的缺陷，深入研究了基于部分传输序列（PTS）方法的峰均功率比降低技术。提出了一种改进的增强迭代算法PTS（EIA-PTS）技术。与原始PTS（O-PTS）相比，EIA-PTS技术可以降低计算复杂度。仿真分析表明，O-PTS方法的计算复杂度随着子块个数和相位因子个数的增加呈指数增长，而EIA-PTS技术的计算复杂度基本保持稳定，低于O-PTS方法。在现有EIA-PTS技术的基础上，提出了一种改进的EIA-PTS-Clipping联合峰均比降低技术，将EIA-PTS技术与限幅技术相结合。仿真结果表明，EIA-PTS-Clipping联合PAPR抑制技术与EIA-PTS技术相比，能更好地兼顾光OFDM系统的误比特率性能和PAPR抑制效果，进一步提高PAPR抑制性能，具有较高的应用价值。
Abstract. According to the defect of the high peak-to-average-power ratio (PAPR) in optical orthogonal frequency division multiplexing (OFDM) systems, the PAPR reduction technology based on the partial transmission sequences (PTS) method has been deeply studied. An improved enhanced-iterative-algorithm-PTS (EIA-PTS) technology is proposed. The proposed EIA-PTS technology, compared with the original PTS (O-PTS), can reduce the computational complexity. The simulation analysis shows that the computational complexity of the O-PTS method grows exponentially with an increase in the number of both subblocks and phase factors, while the computational complexity of the EIA-PTS technology basically remains stable and is lower than that of the O-PTS method. On the basis of the proposed EIA-PTS technology, an improved EIA-PTS-Clipping combined PAPR reduction technology that combines EIA-PTS technology with clipping technology is proposed. The simulation result shows the proposed EIA-PTS-Clipping combined PAPR reduction technology, compared with the previous proposed EIA-PTS technology, can further improve the PAPR reduction performance and has a higher application value because it can have a better tradeoff between the bit error rate performance and PAPR reduction effect for optical OFDM systems.
