Evaluation of effects of MZM nonlinearity on QAM and OFDM signals in RoF transmitter
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.
