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.

A Digital Audio Broadcasting (DAB) Satellite System provides optimized service and guarantees a high-grade quality service for hundreds of channels. With minimum cost of the radio set and the broadcasting station, this greatly improves radio broadcasting services worldwide, especially in areas involving difficult deployment of conventional relay infrastructures. This paper illustrates the advantages and the feasibility of a DAB system based on geostationary satellites with on-boardprocessinggeneratingsignals of multiple channel per carrier (MCPC) type.

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.

This article explores the use of classical machine learning and Automnl methods to solve the problem of camera identification from photo images in the absence of metadata and limited computational and resource capabilities in on boardcommunications. The experiments were conducted on the well-known Forchheim Image Database dataset using the Python programming language and libraries such as scikit-learn, auto-sklearn, skimage and pandas. The paper discusses the use of a local binary pattern (LBP) descriptor in combination with various filtering methods. A comparison of the classification results for each algorithm using different confidence and performance evaluation metrics was carried out. The experimental results showed that the Auto-sklearn algorithm achieved the best performance indicators when using the bilateral filtering method.
