V-band gapless OFDM RoF system with power detector down-conversion is proposed. We propose and successfully employ a novel Volterra nonlinear compensation to mitigate signal-to-signal beating interference, resulting in 22% data rate improvement with bit-loading algorithm.

This Letter presents a V-band gapless orthogonal frequency division multiplexing (OFDM) RoF system at 60 GHz employing a power detector to support vector signal down-conversion. Additional RF tone is generated and transmitted from a central station to replace the local oscillator at a wireless receiver for power detector down-conversion. To enhance the spectrum efficiency, the gap between the OFDM signal and the RF tone is not needed. However, the down-converted signal will suffer signal-to-signal interference (SSBI). In this Letter, we propose and successfully employ a novel Volterra nonlinear compensation to mitigate SSBI, resulting in a 22% data rate improvement with a bit-loading algorithm.

We demonstrate experimentally, the use of an I/Q Volterra series-based algorithm to successfully compensate for nonlinearities in a wideband mm-wave RoF system having I/Q imbalance. The capacity of the system was doubled from 14.8 Gb/s to 29.6 Gb/s, while fulfilling FEC performance requirements.
