METHOD AND CIRCUIT FOR GENERATING ADDRESSES OF PSEUDO-RANDOM INTERLEAVERS OR DEINTERLEAVERS

摘要

According to the invention, a pair of coordinates (c1, r1) of a rectangular matrix is calculated for a certain index k of an interleaved or deinterleaved sequence of symbols. Said pair of coordinates is corrected so as to take into account fillers in the rectangular matrix. A transformed pair of coordinates (c6, r6) is determined for the corrected pair of coordinates (c4, r5) by means of a matrix coordinate transformation (T1) process. A valid interleaving address or deinterleaving address I (k) is then calculated from the transformed pair of coordinates (c6, r6) at a timing step k.
