摘要
本文提出了一种针对海洋水声信道多途干扰的新的水声通信体制.它将利用信号码元波形参数进行多维信道编码技术和利用信号码元时延值进行信息编码技术融于信号码元的设计中,从而使得本方案具有很强的抗多途时延扩展能力,并可望获得相当高的通信速率.初步的湖上试验结果表明:在1公里左右的水平通信距离上。
This paper describes a new underwater acoustic communication system which is performed in the multipath channel. The multi-dimensional channel coding technique which uses the signal pattern and the information source coding technique which uses the shift of signal time-delay have been combined in the signal code design. So that, the system could have high ability of anti-interference of multipath arrives, and obtain a high data ratio. In the first experiment at a reservoir, successful transmission of 200 bits/s over a 1 km horizontal path was achieved.
