DEVICE TO DECODE REED-SOLOMON CODES Russian patent published in 2012 - IPC H03M13/45 

FIELD: information technologies.

SUBSTANCE: device comprises a buffer data memory, a unit of syndromes calculation, a Galois processor, a unit of discrete Fourier transformation, a unit for searching of weight error positions t+1, a unit of symbol positions sorting, a unit of error values calculation, a summator of Galois field elements.

EFFECT: higher efficiency of errors correction outside the border of the half of minimum distance by using information on reliability of symbols received from the channel.
