It means that this algorithm can minimize nonlinear effects under varying system parameters, but its performance is limited in sub-Nyquist cases. Besides, the use of the back-propagation algorithm improves system performance, reducing up to 3 and 0.7 orders of magnitude of Ici due to channels overlapped has a higher impact concerningīer than nonlinear optical fiber impairments. Nonlinear impairment compensation based on the digital back-propagation algorithm is implemented in theĭsp-based coherent receiver. Ici is assessed regarding bit error rate (īer) at 16 and 32 Gbaud, as a function of several system parameters. ![]() Wdm systems due to two contributions, namely, overlapping among optical carriers and stimulation of nonlinear optical fiber impairments. Abstract: This paper presents a characterization of interchannel interference ( ![]()
