Abstract:
1. A block interleaving method with a block size K and with N iterations of index j, N being greater than or equal to 1, for use with digital data items indexed by a variable k={0, . . . , K−1} in a block interleaver for positioning input digital data items X in an output sequence made up of output digital data items Y in an order determined by an interleaving law I (j) (k) such that Y(k)=X(I (j) (k)), wherein the method comprises the steps of: calculating an intermediate value I calculating the output value I positioning the input digital data items X, using the block interleaver, in the output sequence made up of the output digital data items Y in the order determined by the interleaving law I outputting the output digital data items Y from the block interleaver as a bit stream for modulation.
