DECODING METHOD FOR ALGEBRATIC GEOMETRY CODES AND DEVICE THEREOF

摘要

The present invention relates to a method for decoding an algebraic geometry code at a defined point on a C-type algebraic curve (a, b) represented by an equation F (X, Y) = 0 of degree b in X and of degree a in Y on Fq, characterized in that it comprises the following steps: - calculation of extended error syndromes (sigmaj (i)) associated with a received word (r); - determination of the error values on each component (r (x, y P (x))) of received word r, from the computed extended error syndromes. The invention also relates to devices and apparatuses associated with this method.
