Abstract:
1. A receiving apparatus for receiving signals in a digital telecommunication system, comprising: receiving means for receiving a reference symbol including a plurality of repetition patterns, wherein each repetition pattern includes a number of complex samples, the number of complex samples being the same in each repetition pattern, and wherein one of the repetition patterns is phase-shifted in relation to the other repetition patterns; and synchronizing means for synchronizing the receiving apparatus in the digital telecommunication system using the received reference symbol, said synchronizing means comprising (1) correlation means for cross-correlating said reference symbol received in said receiving means, and (2) detecting means for detecting a phase of each of the plurality of repetition patterns in said reference symbol and a correlation peak that indicates a position of the phase-shifted repetition pattern, wherein said detected phases of each of said plurality of repetition patterns and said detected correlation peak are used in said synchronizing means for synchronizing the receiving apparatus in the digital telecommunication system.
