Study on Ameliorating the SCG-LDPC code for High-speed Optical Communication Systems

摘要：

　　A novel ameliorated construction method of low density parity check(LDPC) codes,based on the construction method of Systematically Constructed Gallager(SCG) (4,k) code,is proposed.This method,compared with the construction method of SCG(4,k) code ameliorated before,has some advantages such as saving storage space and reducing computation complexity in the hardware realization.And a novel SCG-LDPC(3969,3720) code with the same 93.7% code-rate as classic RS(255,239) code and LDPC(32640,30592) code in ITU-T G.975.1 recommendation is constructed by the proposed method.The simulation analysis results show that this novel SCG-LDPC(3969,3720) code has better error-correction performance and lower decoding complexity than those of a classic RS(255,239) code and LDPC(32640,30592) code.Therefore,the SCG-LDPC(3969,3720) code can be better suitable for high-speed optical communication systems.
