ABSTRACT

The theorem on the number of errors, which occurred in the received messages in the case of transmission of the binary Bose-Chaudhuri-Hocquenghem codes over communication channels, has been formulated. A modification of the Peterson-Gorenstein-Zierler method, based on the reduction of the matrix to triangular form, for detecting and correcting errors in the binary Bose-Chaudhuri-Hocquenghem codes has been proposed. The technique has been developed for accelerating calculation in accordance with this modification. A detailed description of the algorithm of decoding the received messages based on the above modifications and techniques is given.

KEYWORDS

Binary Bose-Chaudhuri-Hocquenghem code, Peterson-Gorenstein-Zierler method, matrix in triangular form, primitive element of finite field, error locator.
