Efficient burst error correction method for application in low frequency channels and data storage units

This paper investigates a simple and effective method for the correction of errors that occur in bursts during data transmission in low - frequency channels but also during data storage in magnetic and optical disks. The specific technique is based on the binary weighted checksum which is computed with logical 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 reducing the required redundancy and making use of simple procedures and rules out erroneous correction. Finally, the use of the algorithm is illustrated via the thorough presentation of an example of erroneous data transmission.
