Özet:

Abstract Context. In telecommunications and information systems with an increased noise component the noise-resistant cyclic BCH and Reed-Solomon codes are used. The adjustment and correcting errors in a message require some effective decoding methods. One of the stages in the procedure of decoding RS and BCH codes to determine the position of distortions is the search for the roots of the error locator polynomial. The calculation of polynomial roots, especially for codes with significant correction capacity is a laborious task requiring high computational complexity. That is why the improvement of BCH and RS codes decoding methods providing to reduce the computational complexity is an urgent task.
