This paper theoretically investigates the signal degradation induced by intersubcarrier interference and frequency-selective fading in orthogonal frequency-division-multiplexing radio-over-fiber systems. Turbo codes and bit interleaver technologies are proposed to effectively mitigate unbalanced error distribution because of intersubcarrier interference and frequency-selective fading. Experimental results show that the receiver sensitivities are improved as far as 5 dB after 50-km SMF-28 transmission for 6.25-Gb/s wireless signals on optical generated 60-GHz carrier.read more

TL;DR: By employing the iterative estimation and cancellation technique for the signal-signal beat interference at the receiver, the approach alleviates the need of the frequency gap, which is typically reserved for isolating the SSBI, and saves half the electrical bandwidth, thus being very spectrally efficient.
