Syndrome calculation for the decoding of algebraic-geometry codes on plane Garcia-Stichtenoth curves

In this paper, the basic function field of an asymptotically optimal tower of function fields by Garcia and Stichtenoth is studied, where bases of one-point linear systems can be explicitly constructed. A representation of finite GF(q2)-rational points on the associated plane curve is derived and exploited to develop a real-time hardware architecture for the calculation of syndromes needed in the decoding of AG codes built on this curve.
