<p>The method is such that the Bn symbols of B coded words of n symbols are interlaced while following an order given by the following law: xk = x0 + kp modulo B.n, x0 being the starting rank in the sequence of Bn symbols and p being a prime number with B.n and k taking the values 0 to B.n-1. Successive sequences of B.n symbols can be read in different orders generated by the same law but with different starting points x0 and steps p. Application, in particular, to transmission devices having to resist pulse-action jammers. <IMAGE></p> |
