THERAPEUTIC TECHNOLOGIES IN TELECOMMUNICATIONS
Leader - Doctor of Technical Sciences, prof. T.M. Naryntik
The current trends in the development of fourth-generation (4G) and fifth-generation (5G) mobile communications distribution networks, terrestrial digital terrestrial TV networks, military mission control systems, and anti-terrorism measures involve the exchange of large volumes of data.
Fiber optic networks provide gigabit data rates in many parts of the world. But modern telecommunication networks also need
a similar opportunity to exchange data in places where fiber optic access does not exist or its organization is not economically viable.
Satellite communication can provide communications in remote areas, but can not always guarantee the high speed of transmission needed to maintain
access to modern multimedia services with a large number of users.
Today the actual task is to build high-speed mobile communication networks of the fourth (4G) and fifth (5G) generations using terahertz-fixed telecommunication fixed-radio systems and switching to small cells (microcells, peacock cells and femtocells) that are basic stations with a limited ra
IMPULSIBLE SIGNALS (I-UWB) FOR TELECOMMUNICATION SYSTEMS
Compared to the traditional I-UWB harmonic signals, there are a number of advantages:
- Larger bandwidth of communication channels.
- Significantly less power for terminals.
- Unique high permeability ability.
- Signals are hard to detect, which ensures unauthorized access to transmitted information.
- the possibility of high-precision detection of the localization of terminals (centimeters at distances in kilometers.
- Transceivers can be created in miniature sizes
- The principles of construction of self-organizing radio networks using pulsed ultra-wideband signals that significantly increase the throughput of such networks are developed. Protocols of interaction of subscribers in these networks are developed. The theoretical concept of decentralized management of radio networks with self-organization is created that will not require the creation of a fixed infrastructure.
- An energy comparison of pulsed ultra-wideband signals with traditional satellite and terrestrial routes of different lengths has been carried out, which made it possible to estimate the energy gain from the use of this type of signals.
- The method of "non-energy" reception of pulsed ultra-wideband signals is developed. The receiver circuit is developed on the basis of such an approach to the detection of ultrashort pulses.
- The simulation model of the receiver of pulsed ultra-wideband signals was developed and investigated. A model of the main part of the receiver, the purpose of which is the allocation of pulses from the received signal, is created.

FIBER-OPTICAL AND LASER SENSORS - GONIOMETERS
Leader - Assoc. SV Ivanov
Fiber optic and laser gauges (goniometers) - sensors for measuring the angle of the object, which can be used in many fields of science and technology, as well as in telecommunications (measuring the angle of rotation of antennas).
Creation of this class of devices became possible only with the development and improvement of the elemental basis of quantum electronics. The principle of operation of an optical goniometer is based on the vortical effect of Sagnac.
The interest of foreign firms in optical goniometers is based on their potential applications in many fields of science and technology. These devices can in some cases completely replace expensive expensive electromechanical devices.
The Institute of Telecommunication Systems has developed several types of sensors of different accuracy based on original technical solutions.
