Channel encoding adapted to error bursts

摘要

A method of encoding information symbols comprises a step in which a word v, orthogonal to a matrix H, the element H_alphabeta of which is equal to the value taken by some monomial h_alpha=Y^jXⁱ at the point P_beta of some locating set, is associated with every block of k information symbols belonging to a Galois field F_q. The invention shows how to choose the set of said monomials h_alpha so as to define codes which can be decoded with an algorithm by aggregates of low complexity, and which provides a very good error correction capability, in particular for channels in which the errors tend to occur in bursts. The invention also relates to devices and apparatuses adapted to implement this method.
