This paper proposes a novel algorithm for finding error-locators of algebraic-geometric codes that can eliminate the division-calculations of finite fields from the Berlekam p- Massey-Sakata algorithm. This inverse-free algorithm provides full performance in correcting a certain class of errors, generic errors, which includes most errors, and can decode codes on alge- braic curves without the determination of unknown syndromes. Moreover, we propose three different kinds of architectures that our algorithm can be applied to, and we represent the control operation of shift-registers and switches at each clock- timing with numerical simulations. We estimate the performance in comparison of the total running time and the numbers of multipliers and shift-registers in three architectures wi th those of the conventional ones for codes on algebraic curves. Index Terms—codes on algebraic curves, syndrome decod- ing, Berlekamp-Massey-Sakata algorithm, Gr¨ obner basis, linear feedback shift-register. |
