可变码长串行级联码的激光通信系统设计

Design of laser communication system with variable code length serial concatenated code

针对自由空间光通信易受大气环境的干扰和影响以及不同业务对编码长度的不同需求,提出了一种可变码长串行级联码的光通信方案,设计了一套基于现场可编程门阵列(FPGA)为编译码处理核心的大气激光通信系统,并对系统进行了外场测试,验证了其可行性。

Aiming at the interference and influence of free-space optical communication on the atmospheric environment and the different requirements of coding length for different services, an optical communication scheme with variable code length serial concatenated code is proposed. An atmospheric laser communication system based on field programmable gate array (FPGA) as the core of coding and decoding processing is designed, and the feasibility of the system is verified by field test..
