Zusammenfassung:	A de-rotator and de-interleaver includes (i) a first memory for storing D elements of rotated and interleaved data in D storage locations, (ii) a first addresser for addressing the first memory in order to read de-rotated and interleaved data out of the D storage locations and to write rotated and interleaved data into the D storage locations, (iii) a second memory for storing mD elements of the de-rotated and interleaved data read out of the first memory, wherein the de-rotated and interleaved data read out of the first memory are stored in mD storage locations of the second memory, and (iv) a second addresser for addressing the second memory in order to read de-rotated and de-interleaved data out of the MD storage locations and to write de-rotated and interleaved data from the first memory into the mD storage locations.
