Abstract
A method of transmitting information on a transmission channel associated with a first numerical alphabet that takes into account a matrix n×n with an orthogonal dominant H on a second numerical alphabet including at least three different non-null values, and a set of at least one sub-matrix of the matrix H, each sub-matrix of the set containing a number p greater than or equal to 2 rows of the matrix H. A sub-matrix from the set of sub-matrixes is selected along with a p-tuple of real numbers referred to as a “row of coefficients”, such that the matrix product of the row of coefficients and the selected sub-matrix supplies a sequence of numbers of the first alphabet, in order to represent the information to be transmitted. In addition to being orthogonal, matrix H is preferentially balanced.
