This article clarifies the parameters of a quantum-resistant algorithm based on AG codes. This algorithm was proposed in previous works by the authors to counter the quantum threat when designing various on-boardsystems. The article describes the procedure for quickly decoding the corresponding codes, estimates the key length and the probability of applying one of the existing attacks to such algorithms. This work can be useful for increasing the security of arbitrary Internet of Things systems. .

field Programmable Analogue Array (FPAA) technologies can offer an analogue platform for a vast number of applications, including communication circuits requiring adaptive processing. The subject of this paper deals with the problem of generating and processing of base-band communication signals using a reconfigurable platform based on FPAA technology. In the experiments it was used AN221E04 circuit included in Anadigmvortex - AN221K04 development board and connected to PC through a serial interface. Also it was used the software tools from AnadigmDesigner2 that allows complex circuits to be designed with a simple drag-and-drop graphical interface. Especially analog modulators and demodulator were implemented, but the capabilities ofthe circuits offer great possibilities for more elaborated modulation schemes.

The article discusses signals with amplitude-phase modulation used in special-purpose communication networks. A description of the transformation of the structure of spectrally effective radio signals for amplification in nonlinear power amplifiers is given and the element base for its implementation is considered. Simulation of the application of the transformation of the signal structure in the baseband for nonlinear amplification of spectrally effective narrowband radio signals is carried out.

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.

The article proposes a new method for training athletes competing in team sports, which is based on the processing of video recordings of games and performances in virtual and augmented reality. The system solves the tasks of object detection, tracking and re-identification of athletes, obtaining their three-dimensional pose, their texture and field marking, combining data from different cameras and presentation of the resulting data in three-dimensional space with the possibility of user interaction.

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.
