  • Method for mapping and de-mapping of non-binary symbols in data communication systems
    Patent number: 8732563
    Abstract: A method of de-mapping non-binary Galois field symbols from physical layer code-words in a data communication system, in which at least one physical layer code-word includes portions mapped from more than one non-binary Galois field symbol is provided. The method includes calculating at least a provisional likelihood estimate for values of a first non-binary Galois field symbol having at least portions within a first physical layer code-word, the calculating including selecting a first number of values of a second non-binary Galois field symbol having at least portions within the first physical layer code-word, the first number forming a subset of the possible values of the second non-binary Galois field symbol.
