Abstract :
Distributed impairment compensation for dispersion and nonlinear effects using backward propagation in a wavelength-division multiplexing (WDM) environment is demonstrated. Dispersion compensation is achieved using complex infinite-impulse-response filtering, which significantly reduces the computational load compared to using finite-impulse-response filtering.
