摘　　要：将编码调制技术引入到高速光通信系统中,并结合LDPC信道编码技术,实现一种高速率低误码率的光传输系统,并利用MATLAB及Optisystem软件进行TC-64QAM的高速光通信系统仿真。由仿真结果能够看出,使用该编码调制技术后的光通信系统性能明显得到改善,即在高速率情况下仍然可以获得低误码率性能,且系统复杂度较低。The coding modulation technology is introduced into the high-speed optical communication system, and combined with the LDPC channel coding technology, a high-rate and low-error-rate optical transmission system is realized, and simulation of the high-speed optical transmission communication system of TC-64 QAM is carried out by MATLAB and Optisystem software. It can be seen from the simulation results that the performance of the optical communication system after using the coding modulation technology has been significantly improved, that is, low bit error rate performance can still be obtained under high rate, and the system complexity is low.
