Abstract:
Method of transmitting information on a transmission channel associated with a first numerical alphabet, each number in the first alphabet being proportional to a physical quantity to be transmitted on the channel, the method comprising:conjointly selecting a sub-matrix and a row of coefficients, wherein the sub-matrix is selected from a set of at least one sub-matrix of a matrix with an orthogonal dominant H of dimensions nÃ—n on a second numerical alphabet including at least three different non-null values, wherein each of the at least one sub-matrix of the set contains a number p greater than or equal to 2 of rows of the matrix of H, and wherein the row of coefficients comprises a p-tuple of real numbers, wherein a matrix product of the row of coefficients and the selected sub-matrix supplies a sequence of numbers of the first alphabet, and wherein the selected sub-matrix and the row of coefficients conjointly represents the information to be transmitted; and representing the supplied sequence of numbers by means of a physical quantity to be transmitted.
