Abstract
In this paper a new approach for increasing the performance of burst error correction that occurs during data transmission in low-frequency channels with pulse-code modulation is proposed. The specific technique is based on the weighted checksum which is computed with arithmetic operations. It is shown that the solution proposed not only guarantees the correction of any single error burst but it also lowers the computational complexity so that procedure correction time does not depend on controlled data block length. Finally, the use of the algorithm is illustrated via the thorough presentation of an example of erroneous data transmission.
Highlights
The development of the information transmission technologies in the computer networks and in the telecommunication systems is inseparably connected with the problem of integrity and of ensuring high effectiveness of error detection and correction of errors which occur during data transmission.The dynamic increase in the speed of information transmission in the buses of computer systems and the channels of computer networks brings about stringent requirements for the performance of the hardware implementation of the error detection and correction algorithm: it must ensure the realization of the operations which are connected with the rate of error detection for data transmission.A continuous increase in the speeds of data transmission in the telecommunications network systems is resulted in change of error character and effectiveness criterions of error detecting and correction
It is shown that the solution proposed guarantees the correction of any single error burst but it lowers the computational complexity so that procedure correction time does not depend on controlled data block length
The proposed approach enhances the efficiency of single burst error control in low frequency channels due to the decomposition of the main problem in two parts: the localization of the positions of the corrupted bits in the burst and the localization of the start point of the burst that has occurred
Summary
The development of the information transmission technologies in the computer networks and in the telecommunication systems is inseparably connected with the problem of integrity and of ensuring high effectiveness of error detection and correction of errors which occur during data transmission. The dynamic increase of the data transmission speed has changed the importance such of tradition error control effectiveness criterions as number control bits and possibilities of detecting and correction errors in rate data transmission. The modern tendency for increase of speed and values of data transmission decreases the importance of such tradition error control effectiveness criterions as number control bits. The problem of detecting and correcting burst of errors in rate data transmission is very important and requires attention for the current and future technological developments in computer and telecommunications system. This specifies the urgency and the practical importance of the development of new methods and means to speed up the burst errors detection and correction procedures
