摘　　要：水声信道是一种极其复杂多变的时-空-频变参信道,信号传输中将同时产生随机错误和突发错误,且以密集突发错误为主。为了降低误码率,保证通信的可靠性,文章提出了水声通信中的级连纠错码方案。经过性能仿真分析和湖上实验验证,该方案实用可行。Ocean channel is such a complex environment. Underwater acoustics channel is a memorial channel in which random errors and burst errors occur simultaneously and most of time dense burst errors predominate. The serial concatenated code system is built up to reduce BER and guarantee the communication reliability. The error correcting code is analyzed by simulation and experiments on the lake. The experiments verify that the techniques are advanced.
