METHOD OF DETERMINING VIOLATIONS AND CORRECTING VIOLATED CODES OF BIT POSITIONS IN '1 FROM 4' CODING

摘要

FIELD: information technology.;SUBSTANCE: in the encoding device of the transmitting side of a communication channel, information coming from a source in a binary code is converted to a "1 from 4" code with an active zero; the converted information is generated in form of an array of words which can be presented in the form of a table comprising P₁ rows (words), each comprising P₂ quaternary bits in a "1 from 4" code, wherein like quaternary bits in rows form P₂ vertical columns of the array; a check code, K_r and K_v, is formed for each word and vertical column, respectively, via successive summation of bits of the word and the vertical column without carry over; in the control device, the received information is checked for conformity with the "1 from 4" code and check codes K_r and K_v; upon detecting a fault, the information is corrected and transmitted to the end device.;EFFECT: high reliability of transmitted information and low power consumption.;3 dwg
