So small, so loud : extremely high sound pressure level from a pygmy aquatic insect (corixidae, micronectinae)

, 2011
To communicate at long range, animals have to produce intense but intelligible signals. This task might be difficult to achieve due to mechanical constraints, in particular relating to body size.

Higher-order modulation for acoustic backscatter communication in metals

, 2022
Backscatter communication enables miniature, batteryless, and low-cost wireless sensors. Since electromagnetic waves are strongly attenuated in several scenarios, backscatter communication in metals via acoustic waves can leverage various applications, e.

Research and Development of a Highly Reconfigurable OFDM MODEM for Shallow Water Acoustic Communication

IEEE Access, 2019
Orthogonal frequency division multiplexing (OFDM) provides an effective approach to combat multipath with high bandwidth efficiency for underwater acoustic communication, thus design and implementation of acoustic OFDM MODEMs draw more and more attention.
