Abstract

List decoding of Hermitian codes is reformulated to yield an efficient and simple algorithm for the interpolation step. The algorithm is developed using the theory of Grobner bases of modules. The computational complexity of the algorithm seems comparable to previously known algorithms achieving the same task, and the algorithm is better suited for hardware implementation.
