Abstract
We experimentally demonstrate the photonics-Aided wireless transmission of 4 × 4 multiple-input multiple-output probabilistic shaping 64-Ary quadrature-Amplitude-modulation (PS 64QAM) millimeter-wave signals at D-band (110-170 GHz) over 3.1-m distance with a total bit rate of 1.056 Tb/s and a bit-error ratio under 4 × 10-2. The employment of advanced digital-signal-processing techniques, including probabilistic shaping, the Nyquist shaping, and look-up-Table predistortion, significantly improves the transmission capacity and distance as well as the system performance. To the best of our knowledge, this is the first time to realize >1-Tb/s millimeter-wave signal wireless delivery.
