Aerospace Instrument-Making Annotation << Back METHOD OF ERROR CORRECTION IN DEVICES FOR TRANSMITTING AND PROCESSING INFORMATION OF TELECOMMUNICATIONS SYSTEMS UNDER THE INFLUENCE OF EXTERNAL AND INTERNAL INTERFERENCE A.A. Pavlov, A.N. Tsarkov, A.Yu. Romanenko, A.A. Mikheev The necessity of error detection and correction in digital data transmission systems is justified and the requirements for methods of ensuring their noise and fault tolerance are determined. A regular procedure for adapting the code that corrects single byte errors that occur in the physical environments of communication channels for detecting and correcting byte errors in arithmetic-logic devices of processors of digital data transmission systems is proposed. The regularities that determine the relationship between arithmetic and logical operations and the values of the control bits of the linear code relative to these operations are revealed. It is shown that these regularities allow us to formulate rules for obtaining the values of corrections to the control bits of the code for detecting and correcting single byte errors when using an algebraic linear code with syndrome decoding. The proposed method of protection against single byte errors of information processing devices makes it possible to minimize the impact of encoding (decoding) information on the speed of the arithmetic-logical device of the processor by replacing the cyclic information encoding procedure with an algebraic one with syndrome decoding. Keywords: digital data transmission system, correcting algebraic linear code, single error bytes, information bits, control bits, algebraic operations, logical operations.
