We experimentally demonstrate a W-band optical-wireless transmission system over 160-m wireless distance with a bit rate up to 40 Gb/s. The optical-wireless transmission system adopts optical polarization-division-multiplexing (PDM), multiple-input multiple-output (MIMO) reception and antenna polarization diversity. Using this system, we experimentally demonstrate the 2×2 MIMO wireless delivery of 20- and 40-Gb/s PDM quadrature-phase-shift-keying (PDM-QPSK) signals over 640- and 160-m wireless links, respectively. The bit-error ratios (BERs) of these transmission systems are both less than the forward-error-correction (FEC) threshold of 3.8×10.
我们通过实验展示了一种在160米无线距离上的W波段光无线传输系统，其比特率高达40 Gb/s。该光无线传输系统采用光偏振分复用（PDM）、多输入多输出（MIMO）接收和天线偏振分集。利用该系统，我们通过实验分别展示了在640米和160米无线链路上2×2 MIMO无线传输20 Gb/s和40 Gb/s的偏振分复用正交相移键控（PDM-QPSK）信号。这些传输系统的误码率均低于3.8×10的前向纠错（FEC）阈值。
