摘　　要：进行光传输系统发展趋势和级联码理论分析与探讨之后,基于传统级联码方案,提出一种适用于光传输系统的新颖交织型级联码方案。通过仿真分析表明:相对于传统级联码方案而言,由该新颖的交织型级联码方案所构造的级联码是一种纠错性能优良、冗余度适中、易于实现的码型。因而,这种改进的新颖交织型级联码方案更适用于光传输系统的实际应用要求。Based on the analysis on the development trend of optical transmission systems and the theory of concatenated code, a novel coding scheme of interleaved type concatenated code is proposed based on the traditional coding schemes. The simulation analysis shows that the novel interleaved type concatenated code, compared with traditional coding schemes, is a more excellent concatenated code with the advantages of batter error-correction performance, moderate redundancy and easy implementation. Therefore, the improved novel coding scheme is more suitable for practical applications of optical transmission systems.
