Berezkin A. Methods and software tools to increase the efficiency of radio signals in mine tunnels

The object of the research is the process of distribution and reception of radio signals in the mine tunnels. The aim is to develop methods, models and software for solving problems of radio planning, effective reception of radio signals based on the identification of "their" radio signal Research methods are methods of theory of radio wave propagation, mathematical and computer modeling, theoretical and experimental research, methods of high-performance computing. The practical results are that the placement of radios is simplified, the quality of reception in mine tunnels is improved, the choice of microprocessor is simplified when designing a panoramic radio receiver for working conditions in a mine. Scientific novelty: 1. For the first time a method of simplifying radio planning tasks in mine tunnels based on the use of a mathematical model of electromagnetic field energy at a point where the total function of field energy at a point is formed as an additive sum of field component functions, and tuning coefficients are determined by least squares; 2. Improved the method of identification of radio signals based on the criterion of "coincidence of the phase portrait"; 3. A mathematical model for estimating the computational load of an adaptive panoramic radio receiver for operating conditions in mine tunnels is proposed. Implemented at enterprises for mobile communication technologies, positioning of personnel, vehicles, in projects of Data Express LLC. Field of application - industrial radio communication
