INTERLEAVER AND METHOD FOR INTERLEAVING A DATA BIT SEQUENCE

摘要

The interleaving method and the interleaver (IL) of the invention interleave an input data bit sequence (BS) of M data bits by using an interleaving memory IM having a number of memory locations (IM00, IM01) for storing the M data bits of the input data bit sequence. Each memory location (IM00, IM01) stores a respective code symbol consisting of a predetermined number N of data bits selected from the input data bit sequence (BS). The usage of the symbol-wise storage of the data bits of the input data bit sequence (BS) allows to increase the interleaving speed and to decrease the memory requirements in the interleaving memory (IM).
