摘要
针对光正交频分复用(O-OFDM)系统具有较高的峰值平均功率比(PAPR)问题,介绍了目前降低光OFDM系统PAPR的主要方法及其优缺点,包括预畸变类技术、编码类技术和概率类技术。阐述了限幅方法和部分传输序列(PTS)方法的基本原理,并对其PAPR抑制效果进行了仿真分析。
For the high peak-to-average power ration (PAPR) of optical orthogonal frequency division multiplexing (O-OFDM) system, the main schemes and their strengths and weaknesses are introduced, including pre-distortion techniques, coding techniques, and probability techniques. The principles of clipping and PTS algorithms are expounded. In addition, their PAPR reduction validity is analyzed by simulation.
