Abstract :
Intermodulation distortion and clipping noise due to laser diode nonlinearity constitute a major source of interference and noise in radio over fibre systems. These noise are known to be signal level dependent. This paper proposes an analytical model for evaluating performance of radio over fibre systems. The numerical results presented showed a 4.5 dB improvement in performance when the effect of mobile radio discontinuous transmission mode on intermodulation distortion and clipping noise are taken into account
