This method consists of two algorithms, one for the preparation phase of the code, and the other one for the decoding process. Starting from a parity check matrix of the linear code, our approach enables the user to decode a given codeword in a number of steps proportional to its length. Complexity analysis, complete examples and comments about the application of FGLM techniques to linear codes are also given in this paper. =sponsor= This work was done while the first author spent the academic year 1999/2000 at RISC-Linz, supported by \"OAD =keywords= error-correcting codes, linear codes, FGLM, Groebner bases
