摘　　要：前向纠错码可以有效的增加远程光纤通信系统的系统容量和传输距离。构造了基于Kirkman三元系的KTS-RA码,并应用于自发辐射(ASE)噪声为主要噪声源的远程光纤系统中。KTS-RA码不仅消除了传统RA码交织器的最短环,而且具有灵活的开销和码率。仿真结果表明,在光纤信道下KTS-RA码性能明显优于传统RA码,且优于RS级联码等传统方法。In high- speed long - haul optical fiber communication systems, FEC codes provide an effective increase of transmission distance and systems capacity. In this paper, we present a new KTS- RA code which is built based on Kirkman triple system （KTS）. The code is applied to optical fiber system in which amplified spontaneous emission（ASE）is the main noise source. KTS - RA code is free of the shortest 4 cycles and has flexible cost and code rates. The simulation results show that KTS - RA codes have advantage over traditional RA code in optical fiber channel and have better performance than that of concatenated RS codes.
