The report presents a new solution to the problem of increasing the energy efficiency of a digital transmission system with multi-frequency modulation and optimal finite signals that do not cause cross-symbol interference at the outputs of narrowband filters in various modem channels. A new method for multi-frequency data transmission based on the space-time transmission and reception of optimal finite signals observed in demodulators of the digital transmission system has been proposed. New data of the spectral-energy efficiency of the developed modem are presented. From a comparative analysis with standard modems, it follows that the modem developed is superior in efficiency to the known modems.

Differentially coherent communication scheme based on the use of chaotic radio pulses as information carriers is considered and analyzed. The developed scheme is easier to implement in microwaves than its analogs, because it contains only short-time delay elements. The communication process is simulated in Matlab environment.

The work presents a solution to the problem of Fano resonant contour characterization in optical biosensors of refractometric type based on ring fiber Bragg gratings with $pi$: -shift. To solve this problem a microwave-photonic method of three-frequency probing of an ultra-narrowband asymmetric Fano contour using symmetrical amplitude-modulated radiation with amplitude-unbalanced sideband components was proposed. In order to characterize the central wavelength, a functional was introduced, which is similar to the modulation index of the beating envelope between the components of the probing radiation. The paper gives the requirements for the sideband frequencies selection so that the unambiguity of the functional is maintained and the maximum sensitivity is achieved in the measurement range, which is defined by the bandwidth of a Fano contour at half-maximum. The paper demonstrates the possibility of expanding the range of sidebands and increasing measurement sensitivity using dual-frequency probing with halved frequency amplitude-unbalanced sidebands and suppressed carrier. The proposed method is compared with the previously applied microwave-photonic solution of two-frequency symmetric probing with equal amplitudes of the sidebands and the suppressed carrier. Using the results of the Fano contour characterization, it is possible to explicitly determine the central frequency, maximum amplitude and its quality factor.

One key use case for a future neural network is mass inter-machine communication for the Internet of things (IoT) domain, which meets a wide range of requirements, from huge bandwidth to extremely low latency and huge heterogeneity of end devices in corporate network. Subsequently, the network shall provide the IoT network domain dedicated slice of the physical network. The network slicing concept describes a logical segment of a physical network that guarantees a set of QoS requirements. Importantly, they are provided for end-to-end communication to the core of the network. We discuss the neural network model design for telecommunication corporate network monitoring. Based on the applied analysis, it can be concluded that the neural network approach is used to optimize the corporate network structure.

Currently, there is a need to develop a digital antenna array because of the increasing demands placed on wireless telecommunications systems. The use of digital antenna arrays allows obtaining an opportunity for multiple beam patterns in given directions. The paper gives the notion on how the construction and operation of a digital antenna array made. This device consists of a cylindrical antenna array composed of directional antenna elements or emitters. The carrier frequency is 315 MHz. This device evaluates the spatial coordinates of the radio signal sources, and then calculates the corresponding complex weight generating the beam pattern with the main lobe pointed to each source place. All work takes place in a block of digital signal processing implemented on elementary computing units, such as complex multipliers and adders. The example of a code-division-signal model will show the advantage of the use of such a device.
