Research on the Performance of the Interleaved Concatenated Code for Optical Communication Systems

The error-correction performance of the interleaved concatenated code and the single-level concatenated code in optical communication systems are theoretically researched, simulated and analyzed. It can be found that the error-correction performance of interleaved concatenated code is almost equal to that of the single-level concatenated code, but the net coding gain (NCG) and error-correction performance of interleaved concatenated code is much higher and better than those of RS (255,239) code which is the classical code-type. Furthermore, the redundancy of interleaved concatenated code is extremely lower than single-level concatenated code, and it has the better performance on the burst error-correction. Therefore the interleaved concatenated code is more suitable for optical communication systems.
