Samenvatting
We present, both numerically and experimentally, the nonlinearity effect of the intensity modulator in RoF transmitters through the comparison between single-carrier QAM and multi-carrier OFDM signals. The acceptable RF power level of the multi-carrier OFDM signal is 2 dB less compared with the single-carrier signal for the same EVM penalty of 1%, indicating the degradation due to inter-modulation products caused by the modulator nonlinearity for OFDM RoF systems.
