Non-data-aided joint bit-rate and modulation format identification for next-generation heterogeneous optical networks
A technique for joint bit-rate and modulation format identification is proposed. The technique utilizes artificial neural network and asynchronous delay-tap plots. Estimation accuracies above 99.7% are obtained for several different signal types. The technique can be used in receivers as well as at the intermediate network nodes.
