Abstract :
We describe a new effective technique for the adaptive adjustment of the control parameters of any structure of polarization-mode dispersion compensator, such as, e.g., those based on a cascade of polarization controllers and polarization-maintaining fibers. This technique is based on the mean square error between the photodetected signal and the decided symbol and allows us to obtain fast convergence and a lower outage probability with a very limited complexity.
