通过对光通信系统的发展趋势和级联码的理论进行分析后,对光通信系统中传统级联码、并行型级联码和交织型级联码三种级联码的性能进行了深入研究。通过理论分析与仿真结果表明:传统级联码冗余度过大,并行型级联码的译码实现过于复杂,而交织型级联码是一种纠错性能优良、冗余度适中、易于实现的码型,更适用于光通信系统。
通過對光通信繫統的髮展趨勢和級聯碼的理論進行分析後,對光通信繫統中傳統級聯碼、併行型級聯碼和交織型級聯碼三種級聯碼的性能進行瞭深入研究。通過理論分析與倣真結果錶明:傳統級聯碼冗餘度過大,併行型級聯碼的譯碼實現過于複雜,而交織型級聯碼是一種糾錯性能優良、冗餘度適中、易于實現的碼型,更適用于光通信繫統。

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.
