本文论述了应用于水声信道的级联TCM编码方案,并在水声信道模型中对其进行了性能仿真。通过与各种状态下TCM的比较,证明级联TCM编码方案在同一水声信道模型下能获得相对较大的编码增益,对水声通信系统的纠错性能有较大改善。
This paper discusses the cascaded TCM encoding scheme applied to underwater acoustic channels and simulates it in the underwater acoustic channel model. Compared with TCM under various states, it is proved that the cascaded TCM encoding scheme can obtain a relatively large encoding gain under the same underwater acoustic channel model, and greatly improves the error correction performance of the underwater acoustic communication system.
