In this paper we present the integration of unmanned aerial vehicles (UAV) networks and software-defined networks (SDN). The research introduces two ways to construction UAV networks with SDN technology, first way when the base station executes the functions of the SDN controller, and the second way when the UAVs are used as SDN controllers. In this paper, it is proposed to consider in more detail the method of organizing a UAV network for collecting data from sensory fields. At the same time, the network structure of the UAV is distributed over several clusters, which, in turn, requires the choice of the head node for interaction with the SDN controller.
Keywords: unmanned aerial vehicles, UAV networks, SDN.

The reasons for the unsuitability of the current criteria for assessing the electromagnetic environment for the new conditions, as well as the contradictions between the real telecommunications structure and existing legal and regulatory mechanisms for regulating, limiting and controlling technologies are considered. It is concluded that it is necessary to revise and reorganize the current electromagnetic safety system and to introduce direct legal law regulation.
Keywords: electromagnetic safety, stochastic electromagnetic process, territory monitoring, hygienic criteria, control and regulation.

The convergence of telephone communication networks and data transmission networks is becoming increasingly relevant with the development of new technologies. One of the initial stages of this process is the use of subscriber identification technologies in various networks. The possible implementation of such a technical solution in Russia using ENUM protocols, its implementation for the operation of a database of portable subscriber numbers is being considered. The results of an experimental test of the possibility of making a telephone call between two independent segments of the VoLTE network using ENUM technology, and the results of the operation of a test node of a decentralized record storage system used in the process of interaction over the ENUM protocol are presented.
Keywords: convergence of communication networks, subscriber identification, ENUM protocols.

The article presents the results of the development and research of an adaptive algorithm for detecting radio signals in cognitive radio systems. The results of the theoretical and experimental comparison of the developed algorithm with the classical energy detector are presented. It is shown that the proposed algorithm with an adaptive threshold is more effective than the algorithm with a fixed threshold when detecting signals with uneven energy.

The issue of synthesis of an invariant of an additive transformation group using group shift operations is considered. The vector of directions of the line of invariant distance is determined, which is invariant to the influence of additive interference. Invariant modulation and demodulation algorithms based on the composite invariant of the communication channel are presented. An example of vector representation of distortions of reference and information signals by additive interference is given and a block diagram of an invariant receiver is presented.

The paper considers the problem of increasing the noise immunity of element-by-element reception of signals obtained as a result of nonlinear code multiplexing of phase group sequences. This is achieved by increasing the number of phases and amplitudes, followed by optimization of the amplitude and phase group sequences. To reduce the number of calculations during the optimization of the group sequences it is proposed to limit ourselves to the possible values of amplitudes and phases of group sequences that are closest to the elements of the total CDMA sequence from which the group sequence is formed. The results of calculating the noise immunity of element-by-element reception and reception of the obtained amplitude and phase group sequences as a whole are presented.
Keywords: nonlinear code multiplexing, phase group sequence, element-by-element reception, energy gain.
