摘要

A device which enables different spreading factors while preserving a comnmon scrambling code, in particular for transmission in a code division multiple access cellular mobile radio system. The device including a grouper for grouping the various data symbols of a kth incoming sequence (k=1, . . . , K) into different blocks of Q_MAX/Q_Ksymbols, and a spreader for spreading K incoming sequences with K respective spreading codes of respective length Q_k(k=1, . . . , K) which is a sub-multiple of a maximum length Q_MAX, wherein the spreader spreads the blocks from the kth incoming sequence (k=1, . . . , K) with the corresponding code of length Q_kto obtain a spread sequence including different spread blocks of length Q_MAX. The device further includes a scrambler for scrambling each of the K spread sequences obtained in this way using a scrambling code of length Q_MAX.
