Keywords: network simulator, data transmission network, one-time encryption keys, routing, forced routing, private network.
An algorithm for establishing a connection in the transport part of a special-purpose zone data network simulator has been developed, which allows simulating the operation of a united network over a single connection (switched virtual channel, SVC) in several private networks. The algorithm includes a centralized forced routing procedure. A method of determining one-time encryption keys for protecting forced routing generation messages and establishing an SVC is proposed. When performing these functions, the keys must be one-time for each established SVC in each private network in each section of the data transmission network between two adjacent devices. The use of the proposed method is shown for a large number of SVCs installed in several private networks on a simulator of one zone network, as well as on a simulator of the hierarchical structure of a national network with several zone networks.

It is shown that to ensure the goal of creating control systems and communication systems, it is necessary to fulfill certain requirements and target settings that are set at the design stage. To ensure the fulfillment of the goals of the systems in the process of their functioning, functions supported by time, material, and human resources are implemented. On the basis of the analysis method, the problem of maintaining the functional stability of the communication system is considered, the influence on it of disturbances in the functioning of critically important objects under the influence of various destabilizing factors and control actions is noted.

Keywords: combination, hybrid, direct spectrum expansion, frequency hopping, initial acquisition.
An algorithm for implementing initial synchronization (search) in spread spectrum communication systems based on the use of a combination of pseudorandom adjustment of the operating frequency, specified by a linear pseudorandom sequence, and direct spectrum expansion is considered. It is shown that the establishment of double initial synchronization is possible on the basis of a fast recurrent search algorithm with practically no increase in its complexity. The proposed solution is tested on a simulation model, the obtained quantitative data confirm its effectiveness.

Keywords: sound channels of broadcasting and amplification, deep localization.
It has been shown that the use of modern multi-microphone technologies of primary sound signals processing leads to the destruction of the «deep» localization of the sound picture in sound broadcasting channels and during sound amplification. Digital signal processing methods allow you to supplement the sound consoles with programs of controlled time delay signals from microphones and groups of microphones, as well as in the reverberation channel. The values of time delays of signals from sources in real performance are analyzed and similar delay values are selected, which provide a deep perception of the sound picture and smoothness of their adjustments. The introduction of special indicators of the 2D/3D location of sound sources perceived by the listener is recommended.
