US Patent 7461329 Channel encoding adapted to error bursts

A method of encoding information symbols comprises a step in which a word v, orthogonal to a matrix H, the element Hαβ of which is equal to the value taken by some monomial hα=YjXi at the point Pβ of some locating set, is associated with every block of k information symbols belonging to a Galois field Fq. The method chooses the set of monomials hα 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. Devices and apparatuses adapted to implement this method are also disclosed.
