ABSTRACT:
Interleaver for scrambling an information word, the information word having a multitude of digits, for obtaining a permuted information word. The interleaver includes a first interleaver stage for a row-by-row arranging of the digits of the information word in a plurality of first rows and first columns, and a second interleaver stage for scrambling the digits of one of the first rows by interchanging at least two digits of the one first row in order to obtain a first scrambled row, and for replacing the one of the first rows by the first scrambled row. The first interleaver stage is configured for reading the first row, which is replaced based on the first scrambled row, in a column-by-column manner in order to obtain the permuted information word.
