摘要： A coding device that supplied code words, the symbols of which are capable of modulating a physical quantity on a transmission channel making use of symbols of a first alphabet. The decoding of these words uses symbols of a second alphabet containing the first alphabet, the cardinal of the second alphabet being strictly greater than that of the first alphabet and not being an integer power of the cardinal of the first alphabet. The coding device has an input of the “primary” symbols belonging to the first alphabet, a processor which determines redundant symbols capable of allowing decoding of the code words formed from primary symbols and redundant symbols, by a decoder working on the second alphabet, and solves a system of equations expressing the constraints to be met so that the redundant symbols are in the first alphabet, and an output of the symbols of the code words.

摘要： A transmission device has labeling means adapted to map each symbol of a first alphabet to secondary digital data belonging to a second alphabet having Q symbols, Q being strictly greater than P, wherein P symbols of the second alphabet each exclusively represent one and only one symbol of the first alphabet. A coder determines redundant data belonging to the second alphabet, using coding rules that take into account the secondary digital data. A transmitter modulates a physical quantity into a series of signals each capable of taking a number P of different values, and according to transmission rules successively representing the digital data to be transmitted and the redundant data.

摘要： A device for transmitting digital data includes a selector which selects certain digital data couples which follow each other, a mapper, which, in accordance with a set of rules, maps each digital data couple selected to an amplitude couple, and a transmitter which transmits a signal in quadrature, the two components of such signal being modulated by the first and second amplitudes, respectively, of the amplitude couple. The set of mapping rules includes a rule that states that when the estimated probability that two amplitude couples will be confused, after the transmission has occurred, is greater than a certain value, then the digital data couples corresponding to the two amplitude couples have first or second digital data items whose value is the same.
