The modified method of efficiency estimation for information transfer systems

The paper proposes the modified method of efficiency estimation for information transfer systems complementing the A.G. Zyuko’s well-known method. We introduce the new scale of information efficiency. In addition, we provide insights into the correct reflection of frequency, power and information efficiency indexes for the discrete and continuous transfer systems in an area, limited with the Shannon border. Moreover, we estimate the efficiency indexes at the requirements change to integrity of signal reception for different types of modulation.

Correspondence between capacity and productivity of the systems of transmission on the base of a technology UMTS

In this paper, we consider K. Shannon’s description of the channel capacity. On the experimental side, we propose the model of the system for discrete information transfer. We exemplify it by utilizing the UMTS technology and the transformation of original formulas of Shannon’s capacity when the information is transformed on every segment of the model of transmission system.
