摘要：

We have experimentally demonstrated optical orthogonal frequency division multiplexing (OFDM) signal generation by an optical phase modulator and a 40 GHz radio-over-fiber symmetric system with turbo coding technique. The power penalty for the 2.5 Gb/s downlink data carried by 40-GHz millimeter-wave after transmission over 50-km SMF-28 is smaller than 0.5 dB. The OFDM signals without coding and with coding after transmission at a BER of 1 x 10(-3) is -17.5 and -20 dBm, respectively. (C) 2011 Wiley Periodicals, Inc.
