Description: The calculation of indexes of authenticity of passing to information is conducted in ductings with errors which form a group on the basis of the use of mathematical model of Beneta-froylikha. The estimation of the power winning is given from application of the offered coded-theoretical charts in ductings of transmission information with independent errors and errors which form a group. Dependences of probability of erroneous reception of character are considered in a coded-theoretical chart from the convolutional kodas of algebra. The analysis of application of convolutional kodas of algebra is conducted in a поточной coded-theoretical chart.
Keywords: antijamming code, coded-theoretical charts, burst of errors, probability, model
