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。 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/no=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.
