ELECTRONIC CHROMATIC DISPERSION COMPENSATION TECHNIQUES WITH FEED FORWARD AND DECISION FEEDBACK ADAPTIVE EQUALIZATION IN OPTICAL COMMUNICATION SYSTEMS

Abstract We have examined the electronic dispersion compensation in optical communication systems using adaptive filters equalization. We have used least mean square (LMS), recursive least square (RLS) and fast transverse recursive least square (FTRLS) algorithms for equalization. We have also implemented Feed forward and decision feedback equalizer with these algorithms in optical communication scenerio. Results demonstrates that great reduction in bit error rate and improvement in optical signal to noise ratio might be attained by utilizing FTRLS algorithm.
