Study on New Concatenated Code in WDM Optical Transmission Systems
摘要
Abstract
A new concatenated code of RS(255,239)+BCH(2 040,1 930) code to be suitable for WDM optical transmission systems is proposed. The simulation results show that this new concatenated code, compared with the RS(255,239)+CSOC(k0/n0=6/7,J=8) code in ITU2T G.75.1, has a lower redundancy and better error-correction performance, furthermore, its net coding gain(NCG) is respectively 0.46 dB, 0.43 dB more than that of RS(255,239)+CSOC(k0/n0=6/7, J=8) code and BCH(3 860,3 824)+BCH (2 040,1 930) code in ITU-T G.75.1 at the third iteration for the bit error rate(BER) of 10-12. Therefore, the new super forward error correction(Super-FEC) concatenated code can be better used in ultra long-haul, ultra large-capacity and ultra high-speed WDM optical communication systems.
