| Abstract: | The effect of the bandpass-preclipping processing on the clipping distortion of AM/M-QAM hybrid fiber-coax network is analyzed. A model for the clipping pulse noise in the preclipping system is developed, and the bit-error-rate (BER) of preclipping system is analyzed. Numerical calculation results show that the clipping-induced degradation of BER performance is reduced by the preclipping processing. |
