摘　　要：在采用正交频分复用技术的可见光通信系统中,由于信号具有较高的峰均功率比会引起系统性能下降,针对这种问题,将基于误差函数的压扩变换方案应用到光OFDM系统中,通过性能分析和软件仿真,有效地改善了系统性能。In VLC systems which adopt OFDM technology,system performance will deteriorate because of high PAPR.In order to solve this problem,this article applies a nonlinear companding technique based on Error Function to optical-OFDM systems,and has verified its effectiveness in reducing PAPR by performance analysis and Matlab simulation.
