中文摘要：
论述了应用于水声通信的双串行级联编码（D-SCCC）技术；针对水声通信在某些应用场合高可靠性要求，通过对误码率（BER）的分析，提出了提高水声通信可靠性的编码设计方法，并在给定的水声信道下进行了仿真．仿真结果表明，相同码率下双串行级联编码与SCCC算法相比，BER瀑布区陡度增大，在BER为10^-5时有0．5dB的编码增益；相同码率下SCCC算法与Turbo码相比，可有效改善Turbo码BER在10^-4～10^-5出现的错误平层，满足了水声通信传输遥控与遥测指令时的高可靠性需求．
英文摘要：
The double-serially concatenated convolutional codes （D-SCCC） method applied in underwater acoustic communication system was studied. In view of the acoustic communication＇ s requirement of high reliability, a new coding method was proposed to improve the reliability of communication through analyzing bit error rate （BER）, and a simulation based on a given underwater channel has been made. Simulations show that at the same bit rate D-SCCC increases the waterfall area＇ s steepness of BER compared with SCCC and has 0.5 dB coding gain in the BER of 10^-5, and D-SCCC improves error-floor of Turbo code＇ s BER when BER is between 10 ^-4 and 10^ -5. This can satisfy requirement of high reliability when the underwater acoustic transmits remote measurement and remote-controlled commands.
