Construction and Analysis on a New Concatenation Code for Optical Communications

Article Preview

Abstract:

Based on the theoretical analysis of both the characteristics for the concatenation code and the two concatenation code-types in ITU-T G.975.1, a new RS(255,223) + BCH(2040,1930) concatenation code for optical communications is constructed and analyzed. The simulation results show that this new concatenation code, compared with the RS(255,239)+CSOC(k0/n0=6/7,J=8) code in ITU-T G.975.1, had a lower redundancy and the better error-correction performance. Furthermore, at the third iteration and at the bit error rate (BER) of 10-12, its net coding gain (NCG) was respectively 0.46 dB and 0.43 dB more than that of RS(255,239)+CSOC(k0/n0=6/7,J=8) code and BCH(3860,3824)+BCH(2040,1930) code in ITU-T G.975.1. Therefore, the constructed RS(255,223)+BCH(2040,1930) concatenation code can be better suitable for optical communications.
