| Abstract(in English) | In the coherent optical transmission systems, adaptive control is required to suppress and compensate for laser phase noise and polarization rotation which are dynamically fluctuated. The large difference between their fluctuation speeds makes the MIMO adaptive equalization unstable. In particular, it is remarkable for quadrature amplitude modulation (QAM) optical signals. Although the improved techniques for MIMO adaptive equalization applicable to QAM signals have been proposed, their performance comparison is a critical issue because huge time and cost are required for exhaustive optimization fo design parameters when the linewidth of laser phase noise and signal-to-noise ratio are varied. In this work, we propose the optimization method using deep learning, called deep unfolding, to apply to the exhaustive parameter optimization in MIMO adaptive equalization. Using open libraries for deep learning, the cost can be remarkably reduced because full-scratch implement is not needed. Using our proposed method, we optimize the design parameters and evaluate the phase tracking performance for adaptive equalization in the conventional MIMO and the MIMO with separated phase compensation. |
