Acoustic modem is one of the key elements of an underwater wireless sensor network
(UWSN). Compared to a terrestrial wireless sensor network (WSN), designing a UWSN is …

We present the design, development, and experimental validation of BlueME, a compact
magnetoelectric (ME) antenna array system for underwater robot-to-robot communication …

The Doppler effect critically degrades the performance of orthogonal frequency division
multiplexing (OFDM) systems in general. This problem is significantly worse for underwater …

The effect of underwater acoustic propagation on the cyclostationary features of
communication signals is modeled and analyzed. Two kinds of channels are considered: the …

In underwater acoustic communications, the received signal is strongly affected by Doppler
shift due to the relative motion between the transmitter and the receiver. The signal is …

Underwater acoustic communication is a key point for performance improvement in an
autonomous underwater vehicle (AUV) swarm. The communication process is essential for …

Communication in underwater environments is extremely challenging: bandwidth limitation,
latency, and extreme packet losses are only the tip of the iceberg. Usually, just a few bytes …

This work proposes a design method for the propulsion system of autonomous underwater
vehicles (AUVs) based on the to be accomplished tasks or trajectories. The method adapts …

In recent years, orthogonal frequency division multiplexing (OFDM) technology has been
widely investigated for both point-to-point underwater acoustic communications and for …

In this article, a filter bank is coupled with a CFAR detector to guarantee an efficient frame
detection in presence of Doppler shift. This work is realized in scope of the NEMOSENS …
