摘　　要：蓝绿激光对潜通信系统大大提高了潜艇的安全深度和通信速度,备受各国军方的重视。为提高信息传输的可靠性,可采用差错控制技术。建立了激光对潜通信仿真系统,分析了RS码、Turbo码、LDPC码的纠错原理和特点,利用Simulink建立了相应的编译码器,对三种纠错码的性能进行了比较。Blue-green laser communication system with submarine can improve the safe depth and communication speed of submarine greatly, and many countries pay attention to develop laser communication system. To improve the dependability of information transmission, the error control technology is adopted widely. In this paper, the laser communication with submarine simulative system is established firstly, and then the error correcting principle and characters of RS code, Turbo code and LDPC code are analyzed. Finally, the corresponding coder and encoder are erected based on Simulink and the performance comparison among three codes.
