ANALYSIS OF TECHNOLOGIES OF AUTOMATIC ESTABLISHMENT OF RADIO COMMUNICATION IN THE DКMН FREQUENCY RANGE

Abstract

The need for constant improvement of radio communication means arises from the growing need for voice and data transmission with high survivability and bandwidth of channels in radio lines, which ensure the exchange of information between military control bodies, military units, units and weapons systems. The problem of increasing the efficiency of the functioning of complex systems, which includes adaptive radio communication systems (ASR), is closely related to ensuring a given level of their quality indicators under the influence of destabilizing factors, intentional and unintentional interference. The study of issues related to the tasks of managing the quality of the functioning of adaptive systems has a number of methodological features built on the paradigms of systems theory and management theory. DКM radio communication technology has taken a huge step forward with the adoption of the MIL-STD-188-141B (1999) radio communication standard, which is an upgrade of the MIL-STD-188-141A (1988) standard, better known as the ALE standard. STANAG 4538 (2009) and Appendix C of the MIL-STD-188-141B standard (2011) define a unified 3rd generation synchronous protocol for data exchange in the DКMН range, which involves the use of a single-channel block signaling sequence for the organization and the functioning of the DКMН connection, as well as the use of mechanisms for increasing the speed of data exchange. The standardization of this protocol by the NATO Agency for Standardization and the US Department of Defense indicates the intention of its widespread use for the organization of DKMH radio communication networks for military purposes, since the automatic establishment of DKMH communication using the third generation technology (3G-ALE) achieves significant improvements in performance indicators radio lines compared to the technology of the second generation (2G-ALE) in connection speed, network size and channel capacity. The task of this study is to analyze automatic connection establishment (ALE) technologies, taking into account the published research materials. The analysis carried out should contribute to the in-depth study of modern radio systems of the DKMH wave range for the purpose of qualitative planning of their use. The purpose of the article is to analyze the technical parameters of adaptive radio communication systems with automatic connection establishment (ALE). The article is published as a reference material for those who study modern radio technologies, investigate the peculiarities of the operation of DKMH radio lines of the wave range, plan and make decisions regarding the deployment of adaptive DKMH radio lines for special purposes. The article contains an overview of adaptive radio communication systems of the 2nd (2G ALE) and 3rd (3G ALE) generations. An overview of the methods of automatic assembly of DКMН radio channels (ALE) used abroad is given. Considered ALE procedures in accordance with MIL-STD-188-141A, ARINC 635, MIL-STD-188-141B, STANAG 4538. A general analysis of the system characteristics of these technologies is provided. Theoretical and experimental results reflecting the advantages and limitations of adaptive signal processing are presented.
