Popis
Shrnutí:Underwater acoustic communication is one of the key technologies in various important research fields, such as ocean geography, offshore oil industry and defense. However, conventional system design can not achieve desirable results, since the underwater channel suffers a lot from multipath propagation and Doppler Effect. In this paper, we aim to introduce a type of coherent underwater acoustic communication system, which combine the joint synchronization and equalization scheme and the joint iterative equalization and decoding technique to combat the severe underwater environment mentioned above. The platform belongs to the physical layer and can take various high layer applications. The proposed system is tested in computer simulated scenarios and experimental data, both of which demonstrate good performance.
