摘要

Symbol pre-distortion is proposed to restrain subcarriers-to-subcarriers beating interference (SSBI) in radio frequency-tone (RF-tone) assisted baseband optical orthogonal frequency division multiplexing (OFDM) system. Simulation results demonstrate that the 40Gbps 16QAM RF-tone assisted baseband OOFDM system with symbol pre-distortion has a 4dB better sensitivity compared to that without pre-distortion after 100km single mode fiber (SMF) transmission.
