摘要 针对光OFDM系统中存在较高的峰均功率比问题,介绍了峰均比的产生原因及描述方法。基于当前降低峰均比方法的分析对比,提出了基于部分传送序列(PTS)和μ律压扩技术相结合的算法来抑制光OFDM系统的峰均比,然后搭建了光OFDM仿真验证系统。 Due to optical OFDM system existing high peak to average power ratio (PAPR), this paper introduces the producing reason and description method of PAPR. Based on the comparison and analysis of current reducing PAPR approaches, a joint algorithm based on partial transmit sequence (PTS) and μ -law companding technology was proposed to suppress PAPR in optical OFDM system. Then a simulation and verification of optical OFDM system was set up.
