    <title language="eng">Data-Aided Multi-Format DSP for Robust Free-Space Coherent Optical Communication</title>
    <abstract language="eng">The increasing demand for fast and license-free satellite feeder links has put optical free-space communications on the research agenda. To compensate for atmospheric turbulence utilizing spatial diversity and post-DSP combining, a DSP is needed that works reliably even at very low SNRs. For this purpose, a custom multi-format data-aided equalizer is developed and its performance is analyzed under various conditions in a dual-polarization coherent transmission system. Numerical simulations and a field test over a 3.2-km free-space optical link are used to validate the DSP design, and show stable DSP performance for a 32 GBd coherent transmission at SNR-values down to 0 dB, even for DP-16QAM modulation.</abstract>
