An apparatus for generating a plurality of output se-quences from an input sequence for obtaining cyclic delay diversity comprises a copier (101) for providing the plu-rality of copies of the input sequence, a cyclic shift element (107) for variably cyclically shifting a copy of the input sequence to obtain an output sequence of the plurality of output sequences, wherein the cyclic shift element (107) is configured for receiving a variable con-trol signal indicating a number of values the copy of the input sequence is to be shifted by, and, in response to the variable control signal, for cyclically shifting the copy of the input sequence by the number of values. |
