✦ Synopsis


We present a fast version of the Feng-Rao algorithm for decoding of one-point algebraic-geometric (AG) codes derived from the curves which Miura and (\mathrm{Ka}-) miya classified as (C_{a b}). Our algorithm performs the Feng-Rao algorithm efficiently by using the Sakata algorithm, i.e., the 2D Berlekamp-Massey algorithm. One can decode the one-point (\mathrm{AG}) codes up to half of the Feng-Rao bound (d_{\mathrm{FR}}) which is greater than or equal to the designed distance (d^{*}). We have proven the validity and the performance of our algorithm in the framework of our own theory, depending little on algebraic geometry. 1995 Academic Press, Inc.
