摘要

In this study, we first present a coherent optical orthogonal frequency division multiplexing (CO-OFDM) system We then proposed an efficient improved LDPC coding method to further improve the performance of the system. The results show that a CO-OFDM system use of the different combination of coding and modulation modes has great influence on the transmission capacity, bit error rate, optical signal-to-noise ratio and anti-dispersion ability of the system.
