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 describes the serial concatenated TCM coding method applied in underwater communication system,and simulates its performance in the channel model. In comparison with the performance of two kinds of TCM,proves that the serial concatenated TCM coding method in underwater communication system can get higher coding gain and further transmission distance ,as well as better coding performance.
