| Abstract: | 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. |
