摘要
A blind modulation format identification method based on fourth-power eigenvalues is proposed for variable-rate optical transmission systems employing probabilistic shaping technology and high-order modulation formats. By using the fast Fourier transformation (FFT) peak value and variance after the received signal passes through fourth-power operation, accurate identification of high order modulation formats with probabilistic shaping and polarization multiplexing can be realized. A high-speed long-haul coherent optical transmission system is built on the platform of the joint simulation to verify the effectiveness of the method.
