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 ...

Reversible Hardware for Acoustic Communications [PDF]
IEEE Communications Magazine, 2020 Reversible computation has been recognised as a potential solution to the technological bottleneck in the future of computing machinery. Rolf Landauer determined the lower limit for power dissipation in computation and noted that dissipation happens when information is lost, i.e., when a bit is erased. This meant that reversible computation, conserving
