水声信道的修正二进制对称信道模型和纠错码的性能分析

GBSC model description of underwater acoustic channel and performance analysis of error correcting codes

介绍了用海试数据建立水声信道修正二进制对称信道（ＧＢＳＣ）模型的方法．用模型计算的错组率分布ｐ（ｎ，≥ｍ）与实测数据吻合较好，说明ＧＢＳＣ模型能较好地描述水声信道，而且ＧＢＳＣ模型具有计算简单使用方便的优点。本文还对不同码长的ＢＣＨ码的性能进行了仿真分析。

The GBSC for modeling underWater acoustic channel to the results of experiments undertaken on underwater acoustic channel is presented in this paper. The block error probability distributions derived from the model are accordig to experiment data very well, indicating that the GBSC can model the channels well, and the GBSC model has the advantage of simplicity and facility. In this paper, the performances of several BCH codes with different lefferent length are analyzed.
