Abstract
A string of K initial symbols is encoded with a code of the parity check type. The K initial symbols belong to a Galois field of order q strictly greater than 2. The code is defined by code characteristics representable by a graph (GRH) comprising N−K first nodes (NC), each node satisfying a parity check equation defined on the Galois field of order q, N packets of intermediate nodes (NIT) and NI second nodes (NSS), each intermediate node being linked to a single first node and to several second nodes by way of a connection scheme. The string of K initial symbols is encoded by using the said code characteristics and a string of N encoded symbols is obtained, respectively subdivided into NI sub-symbols belonging respectively to mathematical sets whose orders are less than q, according to a subdivision scheme representative of the connection scheme (Π).
