A potential underwater communication technology is water communication. Because of the limited physical scale, testing data transmission in laboratory differs from a real-world environment. Albeit fake dispersing specialists have been utilized to reproduce submerged correspondence through channels under various climate conditions after last many years, comparability between test and regular isn...

We consider the problem of communication over a continuous-time Poisson channel subject to covertness constraint: The relative entropy between output distributions when message is transmitted and no input provided must be small. In absence both bandwidth peak-power constraints, we show covert capacity this channel, in nats per second, infinity. When constraint imposed on input, becomes zero, “s...
