摘要：

We demonstrate a novel modulation format independent algorithm for adaptive blind polarization demultiplexing for elastic optical networks(EONs). We compare the proposed algorithm with traditional constant modulus algorithm(CMA) and radius-directed algorithm(RDA), in terms of performance in PM-QPSK,PM-16 QAM and PM-64 QAM coherent system, by simulating in back-to-back(BTB) and transmission sceneries.The simulation result shows that the modulation format independent algorithm can achieve universal adaptive blind polarization demultiplexing for PM-m QAM signals and gain slightly better performance in condition of lower optical signal noise ratio(OSNR). Furthermore, we also carry out experiments to investigate the performance of the proposed algorithm in BTB and 800 km transmission scenarios for 16 GBaud PM-QPSK and PM-16 QAM. The experimental results demonstrate the conclusion of the numerical simulations.
