The problem of capacity increase for radioengineering systems

The article provides analysis of fundamental and applied studies that allows to evaluate the present-day state of information theory. It is revealed that the capacity of real radio-engineering data transmission systems in the absence of noise is limited by the dynamic properties of its linear selective chains. It is also shown what leads to non-Gaussian signal-plus-interference radioenvironment and necessity of effective operation in nonstationary parametric channels of the contemporary telecommunication systems.
