ABSTRACT
A modification of the Peterson-Gorenstein-Zierler method, based on the reduction of the matrix to triangular form, for detecting and correcting occurred errors in q-nary Bose-Chaudhuri-Hocquenghem codes has been proposed. The technique has been developed for accelerating calculation in accordance with this modification. An algorithm for decoding received messages based on the proposed modification is given.
KEYWORDS
