Abstract:
We experimentally demonstrated the detection and compensation of geometric misalignment between transmitters and receivers in underwater transmission of spatially multiplexed time-domain hybrid PAM signals. BERs equivalent to the optimum point were achieved using in-line twin-beam collective monitoring and extracting aberration features through CNN-based machine learning.
