A Novel Method to Compensate Fiber Nonlinearities by Using NAFO Model

This paper proposes the Nonlinear Adaptive Filter bank-based artificial bee colony Optimizer (NAFO) based on Wiener filter for inverse modeling of nonlinear fiber link. Here a third-order inverse Volterra-based nonlinear equalizer (VNLE) is used to compensate the fiber nonlinearities using MATLAB Simulink. In the novel method the Mean Square Error (MSE) of the optical link is measured and compared with IIR-filter based technique. The MSE is reported to be 10-14 value lesser in the novel experimental setup consequently the proposed technique shows enhanced and efficient performance. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.
