Abstract

A novel method based on asynchronous sampling using sampling pulse with wide pulsewidth has been suggested for Q-factor estimation from amplitude histogram. The effectiveness of this method has been demonstrated through numerical simulation. It was found that, there exist a linear relationship between original Q value and the estimated Q factor using sample pulse with certain pulsewidth for both nonreturn-to-zero and return-to-zero signal format. This method is simple and easy to implement. It can be applied to either single channel or multi channel monitoring scheme.
