In the process of construction of new or reconstruction of the existing transmission stations there emerges a problem of determination of their optimum location and technical parameters. In order to define optimum location of a station it is necessary to calculate signal and interference field intensity, taking into account interval profiles fixed in the direction from the station site to the border of the transmission area. The article discusses the solution of the problem how to optimize location of a radio television broadcasting station analyzing service zones and shadow regions of broadcast transmitters using automated computation system and geo information system

Invariant system of information processing based on the linear detector and inaccurate determination of the threshold is considered and quantitative estimation of noise resistance of such kind of system with its posterior comparation with noise resistance of ordinary binary system under non-coherent reception is carried out in the article

Common Many-Core SoC architectures is a quick-growing segment of distributed parallel computing systems. Such systems cannot be effectively programmed manually , however there are only basic instruments and tools for programming. In this article we propose the concept of Many-Core SoC parallel programming. The concept presents visual programming approach, medium-grained parallel program organization with sequential grains and dynamics of parallel computation. The article suggests the set of tools named VIPE: VPL Integrated Programming Environment. VIPE includes strict mathematical formal model basis, visual parallel programming language for medium-grained programs design, toolset for mapping, translating and pre-compiling of the program scheme and the Many-Core SoC simulation software.
