ABSTRACT:
A triangular interleaver (INTERLEAVER) contains a triangular shaped matrix (MAT) of memory cells, each row of which constitutes a first-in-first-out queue. To increase or decrease the interleave depth of the interleaver (INTERLEAVER), the number of interleaved data bytes read from each row of the matrix (MAT) is positively or negatively linearly related to the ordinate number (0, 1, 2, 3, 4) of this row. In this way, impulse noise immunity of transmission of the outgoing interleaved data stream (OID) over a transmission line (TL) is kept substantially independent from transmit rate changes.
