X. Lu et al., CLIPPING-INDUCED IMPULSE NOISE AND ITS EFFECT ON BIT-ERROR PERFORMANCE IN AM-VSB 64QAM HYBRID LIGHTWAVE SYSTEMS, IEEE photonics technology letters, 6(7), 1994, pp. 866-868
We demonstrate that the impulse noise generated from clipping AM signa
ls limits QAM bit-error performance in AM-VSB/M-QAM hybrid optical tra
nsmission systems. A new technique is developed to adequately predict
QAM bit-error rate by defining a measurable parameter which can be obt
ained from impulse counting using a standard spectrum analyzer.
