Antenna polarization diversity for 146Gb/s polarization multiplexing QPSK wireless signal delivery at W-band

We experimentally demonstrate a novel W-band integrated optical-wireless system based on antenna polarization diversity, which can realize 80-km SMF-28 transmission and 2-m 2×2 MIMO wireless delivery for up to 39-Gbaud (146 Gb/s) PDM-QPSK signal at W-band.
