The analysis of the conditions for the provision by subjects (departments, telecom operators, other subjects of information collection and storage) of data on wired and wireless telecommunications infrastructure for their upload to state information systems (IS) and information and analytical systems (IAS) on the example of the IS “General Scheme” and IAS “Register of Communication Services”. The problematic issues of information interaction are revealed and ways to solve them are proposed.
Keywords: information system, information and analytical system, telecommunication infrastructure, state information system, information interaction, communication operator.

COMPENSATOR FOR INTERFERENCE TO RECEPTION OF AN ANGLE MODULATION RADIO SIGNAL, CAUSED BY AN INTERFERING RADIO SIGNAL, WITH A SMALL PROTECTION RATIO
E.L. Pustovoitov, FSBI NIIR, senior staff scientist, Moscow Technical University of Communications and Informatics, associate professor, Ph.D.; pustovoitov@niir.ru
An interfering radio signal at the input of the receiver causes interference at the output of the receiver’s demodulator. It is possible to provide EMC of radio facilities with a fixed band of used radio frequencies using single-channel compensators of radiointerferences for a given type of modulation of the useful radio signal. This article contains description of the compensator of radiointerferences for the case of phase modulated (PM) signal receiver with power of interfering signal compared with the power of the useful radiosignal. This result is achieved by using the information contained in the change in the amplitude of the envelope sum of the useful PM signal and the interfering radio signal at the input of the PM signal receiver.
Keywords: radiointerference, compensator of radiointerference, useful signal, phase modulation.
