N2 - We experimentally demonstrate a hardware-and spectral-efficient large-capacity single-carrier radio-over-fiber system at Q-band (33-50 GHz), employing high-level polarization-division-multiplexing 64-ary quadrature-amplitude-modulation (PDM-64QAM) modulation and heterodyne coherent detection. In our demonstrated system, up to 10-GBd (120-Gb/s) PDM-64QAM vector millimeter-wave (mm-wave) signal at 37.5 GHz can be generated and delivered over 1-m wireless distance, with a bit-error ratio (BER) less than the hard-decision forward-error-correction (FEC) threshold of 3.8× 10-3}. Our demonstrated system can also generate up to 16-GBd (192-Gb/s) PDM-64QAM vector mm-wave signal at 37.5 GHz, with a BER less than the soft-decision FEC threshold of 1× 10-2}. During the receiver digital signal processing, the employment of large-tap decision-directed least-mean-square equalization after carrier recovery significantly improves the system performance. To the best of our knowledge, this is the first time to demonstrate single-carrier PDM-64QAM modulated wireless mm-wave signal delivery.
