The main trends in the development of intelligent transport systems are considered. It is shown that the relevance of the problem of interoperability is increasing in the context of digital transformation of the transport industry. One approach to ensuring interoperability is open systems technology and functional standardization. Methodological approaches to localizing interoperability barriers for further optimization are considered and problems are formulated that can be solved using fuzzy logic calculation algorithms.

This paper continues the study of a post-quantum algorithm built on the basis of algebro-geometric codes, begun in previous works, in the interests of ensuring the information security of the Internet of things systems and on-board communication systems under the conditions of a quantum threat. The paper presents similar codes, the power of which lies above the Gilbert–Varshamov bound, and which can withstand known attacks on algorithms built on the basis of error-correcting codes.

When complex spread spectrum signals are received, their processing is performed by a correlator or matched filter. Thanks to available modern integrated processors and low-noise ADCs, the correlation of the received signal with its copy occurs in digital form. That is, the signal is converted into digital form, after which the calculation of the correlation function is performed using an FPGA or a processor. At the same time, there are simpler ways to find the correlation peak. Modeling one of these methods - using a sliding correlator - is discussed in this article.

In the upcoming 5G and beyond systems, ultra-reliable communications are designed to provide various mission-critical services (industrial automation, remote healthcare, intelligent transportation, etc.). However, the requirements for the reliability of such systems have not yet received clear and unambiguous formulations. In this article, the basic concepts and measures related to reliability are discussed. In addition, some potential research topics and challenges are also identified. These include determining failure criteria, accounting for common cause failures in redundant systems, and selecting an economically feasible level of reliability.

Ensuring flight safety is a priority for the development of modern both civil and military aviation. In particular, navigation systems and on-board information systems being developed to improve safety. Database is the kernel of a modern on-board complex and information system. At the initial stage of design of such systems, it is necessary to construct their functioning effective models. You can use both analytical and simulation models for it. When construct an analytical model of the database of the on-board computing complex, it is necessary to take into account many factors, including the nature of the allocating law of input flows and of the service time of of queries. In this article constructed an example of such model. To show assess the adequacy of the model, a comparison of analytical results and simulation modeling given.

The report discusses the organization of a distributed control system based on continuous logic. The proposed solutions expand the capabilities of cyber-physical systems by increasing their performance and reliability while reducing energy consumption. Promising areas of application are analogue automatic control systems for microelectromechanical and microelectronic devices. The work is aimed at the development of analog computing in the direction of transition to the creation of distributed analog computing structures that continuously synthesize control signals in real time. In analog cyber-physical networks, the temporal gap between physical and computational processes is eliminated. To create hardware control algorithms in real time, continuum logic of interaction between analogue control devices is used. Examples of the use of analogue automatic in robot control systems are given.
