Performance prediction for WDM PM-QPSK transmission over uncompensated links
Coherent communications Nonlinear optics fibers
2015/5/21
We derive closed-form expressions depending on a single fitting parameter for performance prediction of WDM PM-QPSK long-haul uncompensated transmission. Besides general properties, we demonstrate tha...
Nonlinear Effects Prediction in Ultra-Dense WDM Systems Using Volterra Series
All-optical networks Nonlinear optics
2015/6/4
Volterra Series Transfer Function method is investigated to analyze fiber nonlinearities in ultra-dense WDM systems. For 340x1Gb/s at 3GHz grid using intensity-modulated signals, the method enables fa...
Converter end-point prediction model using spectrum image analysis and improved neural network algorithm
spectrum image neural network
2011/5/6
Aiming at the present situation of the steelmaking end-point control at home and abroad, a neural network model was established to judge the end-point. Based on the colour space conversion and the fib...
