Abstract
The invention proposes interleaving binary symbols representing a physical quantity, used in a coding system with at least two recursive convolutional coders each having a divisor polynomial which all share the same given period, or used in a decoding system corresponding to the coding system, comprising writing binary symbols in a table having a first number of columns, equal to the period of the coders, and a second number of rows, performing first permutations of the symbols on each of the columns, and performing second permutations of the columns with each other, the second permutation preserving the property of return to zero of the coders.
