Abstract

The Non-linear Distortion(NLD) in QAM channel of AM/QAM lightwave systems is mainly caused by the clipped Gaussian noise. We use an asymptotic distortion spectrum of clipped Gaussian noise estimating the nonlinear distortion power in AM/M-QAM lightwave system. Also the BER of QAM signal is calculated based on the estimated NLD power. We also compute the BER of QAM signal with the changing of QAM signal power to Gauss noise power ratio(SNRg) and QAM signal power to NLD power ratio(SNLD).
