Turbo-coded 1.25-Gb/s orthogonal frequency-division multiplexing (OFDM) signals in 60-GHz radio-over-fiber system are demonstrated.It can overcome impairments in fibers and extend transmission distance.Experimental results show that the transmission distance of turbo-coded OFDM signals at 1.25 Gb/s with coding (pure bit rate of 830 Mb/s) can be extended by over 30%.
