| 摘 要： | 基于分组Turbo码（BTC）提出光通信系统中一种新颖前向纠错（FEC）码型,即RS（63,60）×RS（63,60）码。仿真表明,在误码率为10-12时,迭代8次的该BTC与ITU-T G.975.1中迭代3次的RS（255,239）＋CSOC（k0/n0=6/7,J=8）相比,其净编码增益要相应增加0.34dB。分析表明该BTC具有分量码短、编/译码速度快的特点,不仅减小了软/硬件实现的复杂度,而且减小了编/译码带来的时延。因而该新BTC能较好地适用于光通信系统。

| Abstract: | Based on block turbo code(BTC),a novel forward error correction(FEC) code of RS(63,60)×RS(63,60) code is proposed for optical communication systems.The simulation results show that the net coding gain(NCG) of RS(63,60)×RS(63,60) code at the eighth iteration is 0.34 dB more than that of RS(255,239)+CSOC(k0/n0 =6/7,J=8) code in ITU-T G.975.1 at the third iteration for the bit error rate(BER) of 10-12.The analysis shows that the novel BTC has the characteristics of shorter component code and rapid encoding/decoding speed,not only reducing the complexity for implementing the software/hardware implementation but also the time delay for the encoding/decoding.As a result,the novel BTC code can better suitable for optical communication systems. |
