摘要

在本研究中，我们首先提出了一种相干光正交频分复用(CO-OFDM)系统，然后提出了一种高效的改进LDPC编码方法，以进一步提高系统的性能。结果表明，采用不同编码和调制方式组合的CO-OFDM系统对系统的传输容量、误码率、光信噪比和抗色散能力有较大影响。

An Improved Coding Modulated in CO-OFDM system and its Performance Analysis

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.
