摘　　要：对副载波复用光波系统中几种限幅失真抑制方法进行了论述和分析 ,特别指出一种性能较好的预编码技术 ,该技术可作为混合 AM- VSB/M-This paper presents a number of techniques that have been developed to reduce clipping-induced nonlinear distortion in SCM lightwave systems, and especially introduces precoding technique. The optical transmitter drive circuits of AM-VSB/M-QAM subcarrier-multiplexed externally modulated system are designed on the basis of this precoding technique.
