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.

This article is devoted to the comparison of user devices from different manufacturers by their main characteristics. The devices of systems for various purposes are considered: meteorological, oceanographic, emergency rescue and fishing systems. To complete the picture, in addition to the currently operating systems without restrictions, the parameters of the system functional, which is currently limited - Argos, are given.

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.

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.
