Reinforcement Learning-Based Adaptive Modulation and Coding for Efficient Underwater Communications

IEEE Access, 2019
In this paper, we propose a reinforcement learning-based adaptive modulation and coding scheme for underwater communications; more specifically, based on the network states such as the quality of service requirement of the sensing message, the previous ...

Representation of acoustic communication signals by insect auditory receptor neurons [PDF]

, 2001
Despite their simple auditory systems, some insect species recognize certain temporal aspects of acoustic stimuli with an acuity equal to that of vertebrates; however, the underlying neural mechanisms and coding schemes are only partially understood.

Timescale-invariant representation of acoustic communication signals by a bursting neuron [PDF]

, 2009
Acoustic communication often involves complex sound motifs in which the relative durations of individual elements, but not their absolute durations, convey meaning.

The Localization Algorithm Based on Symmetry Correction for Underwater Acoustic Networks

IEEE Access, 2019
Underwater localization is an important and fundamental part of the Underwater Acoustic Networks (UANs). The problem we must face is that radio waves and optical waves are heavily attenuated underwater, so acoustic signals become the most common form of ...
