摘要
We proposed and experimentally demonstrated a novel architecture for the downlink of satellite-ground communication system at W-band (75-110 GHz). Radio-frequency transparent demodulation technique and polarization multiplexing technique are used to reduce the ground system complexity. Quadrature phase shift keying signals (30 Gbaud/s) are transmitted over 15 m wireless link and 50 km fiber. The net bit rate of the whole system is 100 Gb/s while 20% overhead forward error correction (FEC) code is used. Bit-rate-error under FEC limit of 2 x 10(-2) is achieved at the optical signal noise ratio of 21 dB.
