Title (EN) GENERALIZED CONVOLUTIONAL INTERLEAVER/DEINTERLEAVER
(FR) ENTRELACEUR/DESENTRELACEUR A CONVOLUTION GENERALISE
Abstract: front page image
(EN)A memory-efficient convolutional interleaver/deinterleaver with a memory array, a write commutator, and a read commutator wherein the commutators perform their respective write and read operations relative to a preselected memory cell after a predetermined delay. The delay is chosen using a modulo-based technique, such that an efficient implementation of a Ramsey Type-II interleaver is realized.
(FR)L'invention se rapporte à un entrelaceur/désentrelaceur à convolution, économe en ressource mémoire, qui comporte un ensemble mémoire, un commutateur d'écriture et un commutateur de lecture qui effectuent chacun des opérations d'écriture et de lecture respectives sur une cellule de mémoire présélectionnée après un délai prédéterminé. Ce délai est choisi selon une technique à base modulo de sorte qu'il est possible de mettre en oeuvre efficacement un entrelaceur Ramsey de type II.
