Performance Analysis on Concatenated Code for Optical Communication Systems

The performances of the three concatenated codes of the traditional type,the parallel type and the interleaved type for optical communication systems are deeply studied after the development trend of optical communication systems and the theory of the concatenated code are analyzed.The theoretical analyses and simulation results show that the inner-outer concatenated code has the greater redundancy and the decoding of the parallel concatenated code are too complex,however,the interleaved type concatenated codes are a superior coding scheme with the advantages such as the better error correction performance,moderate redundancy and easy implementation,therefore,it can better suitable for optical communication systems.
