It is considered the issue of traffic modeling of nanonetwork applications − one of the promising directions of the development of telecommunication systems (IMT-2030). The traffic is analyzed taking into account the existing algorithms of the gateway, which provides the interaction between the nanonetwork and traditional networks. A series of experiments were carried out using the methods of computer simulation. The article concludes that the management of the resources of event-oriented nanonetworks requires dynamic methods.

METHOD OF ANALYSIS OF MISO SYSTEMS IN RADIO RELAY AND CELLULAR COMMUNICATION TAKING INTO ACCOUNT PHYSICAL PARAMETERS OF MULTIPATH CHANNELS

Keywords: MISO systems, space-time block coding, multipath communication channel, signal fading, noise immunity of signal reception, antenna diversity.

А new approach to the study of MISO systems in multipath communication channels is presented. Models of such channels, taking into account the physical laws of radio wave propagation, are used in the analysis of noise immunity of signal reception in radio relay communication, cellular and wireless access networks. The parameters of these models are included in the formulas obtained in the article for calculating the probability of demodulation error of received signals with multi-position quadrature amplitude modulation in MISO systems. The results of the article make it possible to evaluate one of the important parameters of MISO systems with space-time block codes for specific multipath communication channels — the spatial diversity of transmitting antennas, which eliminates the interference of the rays arriving at the receiving antenna.

In this article, we analyze new features of the construction and functioning of the 5G radio access network, as an ecosystem of network positioning of devices. During the analysis of new technologies of the 5G radio interface, which are significant from the point of view of geolocation, fundamental opportunities for improving the accuracy of location estimation through goniometric measurements are identified. The analysis shows the role of network positioning as a tool for increasing the efficiency of 5G networks radio stations due to the spatial filtering of radio signals in the presence and absence of line of sight. The possibilities of compensating for intra-system interference in the conditions of ultra-dense distribution of devices due to adaptive beamforming, which can be implemented through the preliminary positioning of radio stations, are illustrated.

The article proposes an approach to increasing the communication range of domestic transceivers for fiber-optic communication systems (FOOS) with intensity modulation due to forward error correction. An analytical model of FOCS with forward error correction is presented. An estimate of the gain in the information transmission range due to the use of errorcorrecting codes standardized for FOCS is given. The proposed mathematical tools make it possible to obtain the initial data for designing a FOCS or to provide potentially attainable characteristics. A possible variant of the block diagram of an optical transceiver is considered.
