Underwater communication remains beset by a range of problems that stem from the inability of radio waves to propagate well through water. Although low frequency acoustic signals propagate well in water, the available bandwidth is limited. High acoustic frequencies can be used, although they do not propagate very far. This paper reports on high-frequency underwater communication trials using signals...
High data-rate underwater communications can be facilitated by the use of high carrier frequencies. Development of hydroacoustic modems that operate on high carrier frequencies requires knowledge of the channel conditions that may be encountered. Further, the development of mature and reliable systems is expedited by the use of synthetic channel models. Such channel models offer advantages over the...
Underwater acoustic links have low capacity because that operate at low frequencies. These low frequencies are used because they allow long range communication. Networks allow short range links to provide long range communication, eliminating the need for these long link ranges. Therefore high frequencies can be used for underwater acoustic communication. Such high-frequency underwater acoustic communication...
