Abstract:
The invention relates to the encoding/decoding of digital signals, especially using transposition codes involving a calculation of combinatorial expressions. According to the invention, the combinatorial expressions are represented by prime factor power decompositions, and determined by a preliminary reading of pre-recorded representations of decompositions of selected whole numbers.
