中文摘要：
论述了应用于水声信道的网格编码调制技术，分析了影响其性能的主要因素为有效编码长度，最小乘积距离；在此基础上，提出了基于水声信道的8APSK_TCM鳊码调制方法，并在给定的水声信道下进行了仿真，仿真结果表明：8APSK_TCM模式相对于标准的TCM模式在信噪比相同的情况下，降低了系统的误码率，改善了水声通信系统的可靠性。
英文摘要：
The TCM coding method applied in underwater acoustic communication system was studied. The main factors which affected its performance were analyzed, that were the effective code length and minimum product distance. The method of designing asymmetric modulation----SAPSK_TCM based on the underwater acoustic channel was proposed, and the performance of it wassimulated in the Acoustic channel model. Simulation shows that the 8APSK_TCM scheme can bring a coding gain more than the normal scheme. This will improve the performance of underwater acoustic communication.
