The present invention relates to a receiving apparatus ( 1 ) for receiving signals in a digital telecommunication system and a synchronising method for synchronising such a receiving apparatus ( 1 ). The receiving apparatus ( 1 ) comprises receiving means ( 2, 3 ) for receiving a reference symbol comprising at least two repetition patterns, whereby one of said at least two repetition patterns is phase-shifted in relation to the other repetition pattern, and synchronising means ( 5 ) for synchronising the receiving apparatus ( 1 ) in the digital telecommunication system using said received reference symbol. The synchronising means ( 5 ) comprises a cross correlation means ( 16, 24 ) for cross correlating at least one of said two repetition patterns within a cross correlation window having a predetermined length. Hereby, the performance and the accuracy of a cross correlation peak detection can be enhanced for improved synchronisation. |
