Problem statement. In order to increase the efficiency of transmission and reception of information, it becomes necessary to improve the synchronization process of onboard and ground radio engineering systems, which directly affects the noise immunity of information registration. Due to the development and integration of the modern electronic component base, it becomes possible to implement fundamentally new methods of synchronization. This paper proposes a promising method for establishing the symbolic synchronization of radio engineering systems based on the use of additional sequences of the Barker code.

Goal. Increasing the noise immunity of information transmission based on the development of promising methods for establishing symbolic synchronization.

Results. In the course of modeling, the results of estimating the reduced root mean square error of synchronization were obtained when implementing the proposed method of entering synchronization.

Practical significance. The proposed method makes it possible to reduce the reduced root mean square error of synchronization in comparison with the existing approach, due to the use of additional information extracted directly from the received signal.
