Definitions
- a service is said to be "asymmetric" when the rate of information in a direction of transmission is different from the rate of information in the other direction of transmission.
- first addressing means (relating to the interleaving means) further comprise first address determining means, capable of determining the successive addresses for reading and writing in the memory of the data successively delivered by the means interleave. These first address determination means determine said addresses from the values supplied by the intermediate calculation means, the second and third counters, and from the parameter M.
- FIG. 2 illustrates in more detail but still schematically, the internal architecture of a transmission / reception device according to the invention
- FIG. 8 schematically illustrates an embodiment of the second addressing means associated with the deinterleaving means.
- the MDET deinterleaving means incorporated in the operator terminal TO include the branches, the branch of index i 'having a length equal to i'xM' bytes.
- I ⁇ I has been shown, but of course, if the service is an asymmetrical service, I and I 'are generally different, as are M and M'.
- the interleaving means and the deinterleaving means comprise common memory means MM, formed for example from a dual access random access memory.
- the memory space of this memory MM is then broken down into a first memory space ESM1 allocated to the interleaving means MET and into a second memory space ESM2 allocated to the deinterleaving means MDET.
- the interleaving means furthermore comprise first addressing means MAD 1 receiving the parameters I and M, while the deinterleaving means comprise second addressing means MAD2 receiving the parameters I 'and M'.
- the structure of these addressing means will be described in more detail below with reference to FIGS. 7 and 8.
- the means MDA1 also comprise first means for determining the address MD1, which determine the read address ar in the memory and the write address aw in the memory. More precisely, the reading address ar is equal to (adbs + j) xM
- the means MD2 then calculate the reading address ar 'according to the formula (2) below:
