PROCESSING OF PSEUDORANDOM SIGNALS UNDER CONDITIONS OF INTERFERENCE OF UN-KNOWN STRUCTURE
Abstract and keywords
Abstract (English):
The role and importance of modern communication systems in ensuring the national secu-rity of the Russian Federation, including in the conditions of a special military operation to pro-tect the population of Donbass, is shown. The main requirements that modern communications must meet in everyday conditions and in the conduct of hostilities are named. The perspective direction of improvement of military communication systems is considered. A procedure for incoherent reception of pseudorandom signals with differential phase shift keying, when exposed to interference with an unknown structure, is proposed. The error proba-bility bound based on Chernov's inequality is found, which allows us to estimate the noise im-munity of reception under conditions of interference with an unknown structure. It is shown that in a complex interference situation, when the interference has an energy superiority over the signal, it is possible to ensure the necessary reliability of receiving the transmitted useful information. The prospect of applying the results obtained in the theory and practice of improving information transmission systems in power structures is indicated.
