Improving the Security and Reliability of Information-Exchange in Telecommunication Systems with Mobile Objects

Abstract

Based on the analysis of existing approaches to ensuring the security and reliability of information exchange in telecommunication systems with mobile objects, the article notes that the most promising approach to ensure the required performance of these features is the use of signal method. This method is based on the use of combined channel signals as information carriers, created on the basis of special codes and new spectrum spreading methods.

It is shown that a sufficiently large number of different classes of channel signals have been developed today, the use of which as information carrier in the telecommunication systems with mobile objects allows somehow solving the problem of ensuring a given level of security and reliability of information exchange in these systems. At the same time, it is too early to say that this task has already been fully resolved.

In particular, the results of time-frequency features obtained in the research process of a new class of combined signal-code constructions, created on the basis of special sets of radio pulses with linear frequency modulation as the basis designs, allow making a statement that their use as information carriers in telecommunication systems with mobile objects allows providing greater security and reliability of information exchange in these systems compared to the existing classes of combined channel signals, since the developed class of combined channel signals has both the property of invariance to Doppler frequency mismatch and the high level of noise immunity.
