In this paper, using probabilistic methods of the queuing theory for blockchain-based distributed ledger systems mathematical models are constructed that allow calculating a number of characteristics of these systems. The obtained mathematical models are intended for private blockchains and can be used to analyze and optimize the operation of distributed ledger systems in order to ensure their information security.

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 article discusses the problematic issues of the development of intelligent transport systems and the deployment of cooperative intelligent transport systems, taking into account the issues of ensuring the safety of critical infrastructures during digital transformation. Attention is paid to terminology as an effective means of bringing together the opinions of specialists from interdependent but in fact weakly interacting areas of knowledge, as well as a strategy for digital transformation.

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.
