| 摘 要： | 对光通信系统中单级型级联码和交织型级联码的纠错性能进行理论研究与仿真分析后表明:交织型级联码的纠错性能与单级型级联码基本相当,与经典的RS(255,239)码型相比,其净编码增益(NCG)大得多,纠错性能有很大的提升;交织型级联码的冗余度比单级型级联码要低得多,并且还具有比单级型级联码更强的纠突发差错能力。因而交织型级联码更适合光通信系统的实际应用要求。

| Abstract: | 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... |
