Abstract
To interleave a binary sequencerepresented by the polynomial where n=R.M with R≧M, i being an integer which may be written i=r.M+c, r and c being integers, r≧0 and c ε [0, M−1], there is obtained, from the sequence, an interleaved binary sequence*. The interleaved binary data sequence* represented by the polynomial where i*=[r−h(c)].M+c mod n, the h(c) being obtained by the choice of an M-tuple=[h(0), . . . , h(M−1)] of non-negative integers less than R−1 such that, given a predetermined set Π of circulating matrices P of dimension M×M, for any matrix P of Π, the residues modulo R of the components of the vector.P are not nil; and the corresponding choice of an M-tupleobtained fromby the application of a permutation moving h(c) to position L×c mod M, the integer L being relatively prime with M. (It is noted that the above underlining of the variables, and the above single bracketing, is in the original and is meant to be permanent.)
