Vladimir Leontiev, Garib Movsisyan, Arthur Osipyan, Zhirayr Margaryan · Journal of Information Security · 2014
The notion of a communication channel is one of the key notions in information theory but like the notion “information” it has not any general mathematical definition. The existing examples of the communication channels: the Gaussian ones; the binary symmetric ones; the ones with symbol drop-out and drop-in; the ones with error packets etc., characterize the distortions which take place in information conducted through the corresponding channel.
