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。 After analyzing and discussing the development tendency of optical transmission system and the theory of concatenated code, a novel interleaving type concatenated code scheme suitable for optical transmission system is proposed based on the traditional concatenated code scheme. The simulation results show that compared with the traditional concatenated code scheme, the concatenated code constructed by the novel interleaved concatenated code scheme is a kind of code pattern with good error correction performance, moderate redundancy and easy implementation. Therefore, this improved novel interleaving type concatenated code scheme is more suitable for the practical application requirements of the optical transmission system.
