摘　　要：随着通信技术的飞速发展,光通信系统也对传输距离、信道容量以及传输速率有着更高的要求,而想要解决这些问题,则需要研究性能更加优良的FEC码型方案。级联码是诸多码型中纠正突发和随机错误性能较好,且可以保持较低冗余度的一种,因此成为主要研究对象。在国际电联G.975.1标准的级联码基础上提出了两种新型RS-BCH编码,在理论上对其进行了对比分析,并进行相应的建模仿真,其中一种是RS(255,239)码与BCH(31,16)码相结合的级联码,而另一种是RS(255,239)码与BCH(511,448)码相结合的级联码,这两种级联码与单一RS(255,239)编码以及原码的纠错性能相比有较大提升,且后者冗余度适中,易于实现,更加适合于高速传输的光通信系统。With the rapid development of communication technology,optical communication system also has higher requirements for transmission distance,channel capacity and transmission rate.In order to solve these problems,it is necessary to study FEC code scheme with better performance.Concatenated code is a code types which has good performance in correcting burst and random errors,and can maintain low redundancy,so it has become the main research object.Based on the concatenated code of ITU G.975.1 standard,we proposed two new RS-BCH codes,made comparison and analysis in theory,and carried out corresponding modeling and simulation.One was the concatenated code of RS(255,239)code and BCH(31,16)code,and the other was the concatenated code of RS(255,239)code and BCH(511,448)code.The error correction performance of the two concatenated codes has been greatly improved compared with that of the single RS(255,239)code and the original code,and the latter has moderate redundancy and is easy to implement,which is more suitable for high-speed optical communication systems.
