Abstract：This paper studies the principle of underwater acoustic communication system components and the parts fea‐ture ,and proposes to use QPSK modulation technique to design underwater acoustic communication system combining with the impact of underwater acoustic communication channel characteristics of underwater acoustic communication system .The mathematical model of underwater acoustic communication system is established ,and the whole system is simulated and ana‐lyzed with Matlab .Through theoretical studies and simulation ,it is found that QPSK modulation techniques can effectively inhibite multipath expansion in underwater acoustic communication applications ,reduce the error rate of ocean noise ,ensure the reliability of underwater acoustic communication ,and improve communication rate .
