Abstract

Context. Research of a Reed-Solomon codes characteristics for estimation of code and communication channel parameters influence at the reliability
and efficiency of information transmission between of control systems devices are performed. The research object is encoding with using
nonbinary redundant Reed-Solomon codes, the research subject is the theoretical and experimental studies of relation between the Reed-Solomon
codes characteristics and their parameters and transmission channel properties. The purpose is characteristics and properties relation analysis for their
using within encoding and decoding procedures at software of control systems devices.
Methods. The math methods and Reed-Solomon codes building theory are used. The formulas for information transmission reliability estimation
with using Reed-Solomon codes taking into account of code character and individual data bits distortions are received. The dependencies of correct
transmission probability from the code and transmission channel parameters are researched. The dependencies of efficiency indicators (information
rate) of transmission with using the Reed-Solomon codes from code parameters are received and researched. The simulation of control system with
using selected method of the noise stability encoding is done. The encoding and decoding procedures for their adaptation and using within control
systems devises software are realized.
Results. The dependencies of the Reed-Solomon codes reliability indicators (correct transmission probability) and the efficiency indicators (information
rate) from its parameters (Galua field module, number of corrected errors, code shortening degree) are received. The recommendations for
using results for code parameters selecting are done. The control system model with using MathWorks MatLab Simulink is created and configured.
The software modules with encoding and decoding procedures for their practical realization within embedded software of control systems devices are
developed.
Conclusions. The performed research illustrates the dependence of the reliability and efficiency indicators of information transmission from the
Reed-Solomon codes parameters. This allows design reliable control systems with preset level of reliability than provided by a reasonable selection of
Reed-Solomon code parameters
