Abstract

To enhance the capacity and reduce the complexity of Elastic Optical Networks (EONs), a pilot-based shaping entropy identification method based on the Probabilistic Shaping (PS) within Orthogonal Frequency-Division Multiplexing (OFDM) systems is proposed. Shaping entropy identification is achieved by utilizing the pilot insertion method, which reduces complexity and operating costs. The proposed scheme has been validated within a PS-64QAM OFDM transmission system operating at a bit rate of 80 Gbit/s. The simulation results show that the proposed method has the ability to achieve a 100% shaping entropy identification rate when the relative amplitude of the pilot is greater than 1.3.
