摘要
提出一种适用于水声正交频分复用(OFDM)通信中串行级联码结合交织器的差错控制编码方法,采用了信道编码后的正交频分复用技术,可有效解决水下高速数据传输的可靠性问题。介绍了RS与卷积码级联的原理及其在水声通信系统中的应用,在此基础上进行计算机仿真,仿真信道用水声信道仿真软件来模拟,并进行了水池试验。试验结果证明,使用该方案的水声通信系统性能明显得到改善。
A error correction coding method which combines serial concatenated code and interleaver is proposed for UWA communication,and the OFDM technique using channel coding effectively realizes the reliable high-rate data transmission in UWA communication.The principle of RS and convolutional code concatenation as well as its application in UWA system are introduced,based on which computer simulation is conducted.The simulation channel is simulated by underwater acoustic channel simulation software,and tank test is conducted.The result indicates that the performance of UWA communication system using this scheme has been improved significantly.
