A common problem in wireless communication is the existence of multipath propagation. This means that a transmitted signal is received multiple times because of reflections caused by the environment. We present two ways of modeling multipath propagation of an acoustic underwater signal. We discretise these models to solve them numerically....

Unmanned underwater vehicles benefit from communication with a high data rate on relatively small distances (under 100 m). Existing communication methods are not able to provide this or present other shortcomings. Therefore, this bachelor end project focuses on a new type of underwater communication, quasi-static electric field communication....

In this report the analysis of underwater communication using electric quasi-static fields is undertaken, in which key aspects that influence the performance the communication between a transmitting and receiving electrode is examined. A mathematical model was proposed for the transmission and reception of the quasistatic field and the expected...

Flooding-based protocols are a reliable solution to deliver packets in underwater sensor networks. However, these protocols potentially involve all the nodes in the forwarding process. Thus, the performance and energy efficiency are not optimal. In this work, we propose some advances of a flooding-based protocol with the goal to improve the...

The present report assesses the performance of several receiver schemes that attempt to recover as best as possible data transmitted through an acoustic underwater channel modulating a low-frequency single-carrier wave at a high data-rate for this kind of medium. The shifted Known Symbol Padding block structure is considered robust against...

A multiband OFDM transmitter and receiver are presented for underwater communications at low SNR. Compared with a single-band OFDMscheme, the multiband approach leads to a considerable reduction in the receiver complexity. The proposed system has been tested at sea with 16 subbands covering a total bandwidth of 3.6 kHz, at user data rates of 4.2...
