摘要：

In this work, we report modeling and performance investigation of OFDM based Radio over Fiber (RoF) system with different tone signals to combat the different distortions like Intermodulation Distortion (IMD) and Error Vector Module (EVM) etc. It is observed that for low value of RF tone amplitude, the intrinsic IMD3 components are quite small as compared to the fundamental components. But as the amplitude is increased to high value, the IMD3 amplitudes become greater than fundamental components. Optimum value of modulation index is calculated at which fundamental power and IMD3 power becomes equal. We also investigate EVM for three types of modulations (4QAM, 16QAM & 64QAM) against different parameters like SSMF length, MZM bias, drive power and modulation index etc. © 2020, National Institute of Optoelectronics.
